# How Is the Work Done in an Electric Motor?

Many people are under the impression that there are two kinds of energy: work and energy. However, this is not so. In physics, work is simply the energy moved from or towards an object through the application of direct force. In its most simple form, it can be represented as the product of direct force and displacement. There are different kinds of work. Work performed by an arm, for example, involves pushing a ball out of a thrower’s hand, or rotating a rod so that it remains in a particular position. Likewise, work done by a wheel on a truck or car includes rotating the wheel and transmitting force to move a load. And work done by a hydraulic pump is transferring water to a tank, while performing work on an aircraft turbine.

Now consider how the various forms of work are related. The transfer of work between events is described by a force function. This is a mathematical model that describes the relationship between the force that causes one event and the displacement caused by another event. In a way, the force is said to be work if it can be changed from a direct force to a displacement, which is an impulse. This is a force that acts upon an object and changes its location, shape, or level of overall intensity.

A typical force function would look like this: F(x, y), the force that acts upon it, is equal to F(z, y) when the two shapes are parallel and tangential to each other. The force acting on z and y is actually the sum of the individual impulse that is generated due to the force acting on x. If you remove the term “overlapping” from the equation, you get the following definition of work done by a machine: the total amount of work that is done on an appliance (which we assume to be a car) by its electric motor(s). The specific appliance that we are thinking of here is the car. In this case, the term “work done” refers to the entire quantity of work that is done to move the car from point A to point B.

Now let’s revisit our discussion of how a spring moves a pole back and forth. The work done is simply the transformation of kinetic energy (which is actually a sum of potential energy and kinetic energy) into physical energy, which is measured in torque. In our second example, the distance of the spring and the pole are both considered as separate points, with the distance at the pole being measured in meters and the displacement caused by the spring being measured in N units. The result is the torque, which can be expressed as:

The torque can be thought of as the product of the work done by the electric motor and the distance moved by the spring. This way of expressing it is simple and makes it easy to calculate the forces that are acting on a system. For a given system, there will always be a force that acts on it. And the force can be expressed as a function of time and a constant acceleration. Thus, it can be seen that the force that a spring uses to move an object is directly proportional to the time taken to go from zero to the acceleration of the object, and the acceleration can be thought of as a change in velocity.
