You can also use column and row references in a formula. There are two reference styles: The cell that contains the formula is not included in a calculation that uses a reference.

If the cell is part of the reference, it is ignored. You can refer to a table row, column, or cell in a formula by using the RnCn reference convention.

In this convention, Rn refers to the nth row, and Cn refers to the nth column. For example, R1C2 refers to the cell that is in first row and the second column.

The following table contains examples of this reference style. You can refer to a cell, a set of cells, or a range of cells by using the A1 reference convention.

The first column in a table is column A; the first row is row 1. Field codes in Word and Outlook. This means that there is a potential function U x , that can be evaluated at the two points x t 1 and x t 2 to obtain the work over any trajectory between these two points.

It is tradition to define this function with a negative sign so that positive work is a reduction in the potential, that is.

The function U x is called the potential energy associated with the applied force. The force derived from such a potential function is said to be conservative.

Examples of forces that have potential energies are gravity and spring forces. Because the potential U defines a force F at every point x in space, the set of forces is called a force field.

The power applied to a body by a force field is obtained from the gradient of the work, or potential, in the direction of the velocity V of the body, that is.

In the absence of other forces, gravity results in a constant downward acceleration of every freely moving object.

It is convenient to imagine this gravitational force concentrated at the center of mass of the object. Notice that the work done by gravity depends only on the vertical movement of the object.

The presence of friction does not affect the work done on the object by its weight. Let the mass m move at the velocity v then the work of gravity on this mass as it moves from position r t 1 to r t 2 is given by.

Use this to simplify the formula for work of gravity to,. The negative sign follows the convention that work is gained from a loss of potential energy.

The velocity is not a factor here. The work is the product of the distance times the spring force, which is also dependent on distance; hence the x 2 result.

Where P is pressure, V is volume, and a and b are initial and final volumes. The principle of work and kinetic energy also known as the work—energy principle states that the work done by all forces acting on a particle the work of the resultant force equals the change in the kinetic energy of the particle.

Computation of the scalar product of the forces with the velocity of the particle evaluates the instantaneous power added to the system.

Constraints define the direction of movement of the particle by ensuring there is no component of velocity in the direction of the constraint force.

This also means the constraint forces do not add to the instantaneous power. The time integral of this scalar equation yields work from the instantaneous power, and kinetic energy from the scalar product of velocity and acceleration.

The fact the work—energy principle eliminates the constraint forces underlies Lagrangian mechanics. This section focuses on the work—energy principle as it applies to particle dynamics.

In more general systems work can change the potential energy of a mechanical device, the thermal energy in a thermal system, or the electrical energy in an electrical device.

Work transfers energy from one place to another or one form to another. In the case the resultant force F is constant in both magnitude and direction, and parallel to the velocity of the particle, the particle is moving with constant acceleration a along a straight line.

The work of the net force is calculated as the product of its magnitude and the particle displacement. Substituting the above equations, one obtains:.

In the general case of rectilinear motion, when the net force F is not constant in magnitude, but is constant in direction, and parallel to the velocity of the particle, the work must be integrated along the path of the particle:.

For any net force acting on a particle moving along any curvilinear path, it can be demonstrated that its work equals the change in the kinetic energy of the particle by a simple derivation analogous to the equation above.

Some authors call this result work—energy principle , but it is more widely known as the work—energy theorem:. The remaining part of the above derivation is just simple calculus, same as in the preceding rectilinear case.

Remarkably, the work of a constraint force is zero, therefore only the work of the applied forces need be considered in the work—energy principle.

To see this, consider a particle P that follows the trajectory X t with a force F acting on it. Note that n dots above a vector indicates its nth time derivative.

Integrate this equation along its trajectory from the point X t 1 to the point X t 2 to obtain. The left side of this equation is the work of the applied force as it acts on the particle along the trajectory from time t 1 to time t 2.

This can also be written as. This integral is computed along the trajectory X t of the particle and is therefore path dependent.

Now it is integrated explicitly to obtain the change in kinetic energy,. It is useful to resolve the velocity and acceleration vectors into tangential and normal components along the trajectory X t , such that.

Consider the case of a vehicle moving along a straight horizontal trajectory under the action of a driving force and gravity that sum to F.

The constraint forces between the vehicle and the road define R , and we have. As an example consider a car skidding to a stop, where k is the coefficient of friction and W is the weight of the car.

The velocity v of the car can be determined from the length s of the skid using the work—energy principle,. Rolling resistance and air drag will slow the vehicle down so the actual distance will be greater than if these forces are neglected.

Let the trajectory of the vehicle following the road be X t which is a curve in three-dimensional space. Integrate both sides to obtain. The weight force W is constant along the trajectory and the integral of the vertical velocity is the vertical distance, therefore,.

Notice that this result does not depend on the shape of the road followed by the vehicle. This means the altitude decreases 6 feet for every feet traveled—for angles this small the sin and tan functions are approximately equal.

The work of forces acting at various points on a single rigid body can be calculated from the work of a resultant force and torque. To see this, let the forces F 1 , F X n in a rigid body.

This movement is given by the set of rotations [ A t ] and the trajectory d t of a reference point in the body. From Wikipedia, the free encyclopedia.

It is a consequence of the second law of thermodynamics that a thermodynamic system in its own state of internal thermodynamic equilibrium cannot do isochoric mechanical work on an external system; it can do isochoric work on an external system only through long casino niedersachsen non-mechanical forces such as electromagnetic or gravitational.

The amount of energy transferred as work is measured through quantities defined externally to the system of interest, and thus belonging to its surroundings.

In an important sign convention, preferred in chemistry, work that adds to the internal energy of the system is counted as positive.

On the other hand, for historical reasons, an oft-encountered sign convention, preferred in physics, is to consider work done by the system on its surroundings as positive.

One kind of heat transfer, through direct contact between a closed system and its surroundings, is by the microscopic thermal motions of particles and their associated inter-molecular potential energies.

Another kind of heat transfer is by radiation. There are several forms of dissipative transduction of energy that can occur internally within a system at a microscopic level, such as friction including bulk and shear viscosity [17] chemical reaction , [1] unconstrained expansion as in Joule expansion and in diffusion , and phase change.

Thermodynamic work does not account for any energy transferred between systems as heat or through transfer of matter. For an open system, the first law of thermodynamics admits three forms of energy transfer, as work, as heat, and as energy associated with matter that is transferred.

The latter cannot be split uniquely into heat and work components. One-way convection of internal energy is a form a transport of energy but is not, as sometimes mistakenly supposed a relic of the caloric theory of heat , transfer of energy as heat, because one-way convection is transfer of matter; nor is it transfer of energy as work.

Nevertheless, if the wall between the system and its surroundings is thick and contains fluid, in the presence of a gravitational field, convective circulation within the wall can be considered as indirectly mediating transfer of energy as heat between the system and its surroundings, though the source and destination of the transferred energy are not in direct contact.

For purposes of theoretical calculations about a thermodynamic system, one can imagine fictive thermodynamic "processes" that occur so slowly that they do not incur friction within or on the surface of system; they can then be regarded to as reversible.

These fictive processes proceed along paths on geometrical surfaces that are described exactly by a characteristic equation of the thermodynamic system.

Those geometrical surface are the loci of possible states of thermodynamic equilibrium for the system. Really possible thermodynamic processes, occurring at practical rates, even when they occur only by adiabatic work, without heat transfer, always incur friction within the system, and so are always irreversible.

The paths of such processes always depart from those characteristic surfaces. Even when they occur only by adiabatic work without heat transfer, such departures always entail entropy production.

In thermodynamics, the quantity of work done by a closed system on its surroundings is defined by factors strictly confined to the interface of the surroundings with the system and to the surroundings of the system, for example, an extended gravitational field in which the system sits, that is to say, to things external to the system.

A main concern of thermodynamics is the properties of materials. Thermodynamic work is defined for the purposes of thermodynamic calculations about bodies of material, known as thermodynamic systems.

Consequently, thermodynamic work is defined in terms of quantities that describe the states of materials, which appear as the usual thermodynamic state variables, such as volume, pressure, temperature, chemical composition, and electric polarization.

For example, to measure the pressure inside a system from outside it, the observer needs the system to have a wall that can move by a measurable amount in response to pressure differences between the interior of the system and the surroundings.

In this sense, part of the definition of a thermodynamic system is the nature of the walls that confine it. A simple example of one of those important kinds is pressure—volume work.

The pressure of concern is that exerted by the surroundings on the surface of the system, and the volume of interest is the negative of the increment of volume gained by the system from the surroundings.

It is usually arranged that the pressure exerted by the surroundings on the surface of the system is well defined and equal to the pressure exerted by the system on the surroundings.

This arrangement for transfer of energy as work can be varied in a particular way that depends on the strictly mechanical nature of pressure—volume work.

The variation consists in letting the coupling between the system and surroundings be through a rigid rod that links pistons of different areas for the system and surroundings.

Then for a given amount of work transferred, the exchange of volumes involves different pressures, inversely with the piston areas, for mechanical equilibrium.

This cannot be done for the transfer of energy as heat because of its non-mechanical nature. Another important kind of work is isochoric work, that is to say work that involves no eventual overall change of volume of the system between the initial and the final states of the process.

Isochoric mechanical work for a body in its own state of internal thermodynamic equilibrium is done only by the surroundings on the body, not by the body on the surroundings, so that the sign of isochoric mechanical work with the physics sign convention is always negative.

When work, for example pressure-volume work, is done on its surroundings by a closed system that cannot pass heat in or out because it is confined by an adiabatic wall, the work is said to be adiabatic for the system as well as for the surroundings.

When mechanical work is done on such an adiabatically enclosed system by the surroundings, it can happen that friction in the surroundings is negligible, for example in the Joule experiment with the falling weight driving paddles that stir the system.

Such work is adiabatic for the surroundings, even though it is associated with friction within the system. Such work may or may not be isochoric for the system, depending on the system and its confining walls.

If it happens to be isochoric for the system and does not eventually change other system state variables such as magnetization , it appears as a heat transfer to the system, and does not appear to be adiabatic for the system.

In the early history of thermodynamics, a positive amount of work done by the system on the surroundings leads to energy being lost from the system.

This historical sign convention has been used in many physics textbooks and is used in the present article. According to the first law of thermodynamics for a closed system, any net change in the internal energy U must be fully accounted for, in terms of heat Q entering the system and work W done by the system: An alternate sign convention is to consider the work performed on the system by its surroundings as positive.

This convention has historically been used in chemistry, but has been adopted in several modern physics textbooks. This equation reflects the fact that the heat transferred and the work done are not properties of the state of the system.

Given only the initial state and the final state of the system, one can only say what the total change in internal energy was, not how much of the energy went out as heat, and how much as work.

This can be summarized by saying that heat and work are not state functions of the system. Pressure—volume work or PV work occurs when the volume V of a system changes.

PV work is an important topic in chemical thermodynamics. As for all kinds of work, in general, PV work is path-dependent and is, therefore, a thermodynamic process function.

In general, the term P dV is not an exact differential. For a reversible adiabatic process, the integral amount of work done during the process depends only on the initial and final states of the process and is the one and the same for every intermediate path.

If the process took a path other than an adiabatic path, the work would be different. In a non-adiabatic process, there are indefinitely many paths between the initial and final states.

This impossibility is consistent with the fact that it does not make sense to refer to the work on a point in the PV diagram; work presupposes a path.

There are several ways of doing mechanical work, each in some way related to a force acting through a distance. If the force is not constant, the work done is obtained by integrating the differential amount of work,.

Energy transmission with a rotating shaft is very common in engineering practice. Often the torque T applied to the shaft is constant which means that the force F applied is constant.

For a specified constant torque, the work done during n revolutions is determined as follows: A force F acting through a moment arm r generates a torque T.

The power transmitted through the shaft is the shaft work done per unit time, which is expressed as. When a force is applied on a spring, and the length of the spring changes by a differential amount dx, the work done is.

Substituting the two equations. Solids are often modeled as linear springs because under the action of a force they contract or elongate, and when the force is lifted, they return to their original lengths, like a spring.
