# Understanding What is Work # Understanding What is Work

Physics refers to the science of the forces that act on matter to cause it to move. In layman’s terms, work is energy that is transferred from a source to an end with the help of a dynamic force or motive power. The definition of “work” is very broad, but we can give some examples that will better illustrate the concept. From this discussion of work it should be evident that it can be a source of power such as in rocket engines or the movement of particles in the earth’s crust. It can also be a force, for example the force of gravity that keeps everything on earth’s surface up and running.

In physics, work is any energy that is transferred from a source to an end through the application of a particular force or motive power. In its most simple form, it can be represented as the resultant of a certain displacement and force applied to an object. Any source of power can be used to cause an object to move, whether it is a constant speed force such as gravity or a specific momentary force like heat coming out of a hot object. In general, one finds that the work cannot be created nor destroyed. It is only a change from zero to one.

One way to put this process into perspective is through the example of a spring. A spring is designed so that when it is placed at the ends it remains at the same distance apart from the starting point, always moving in the same direction. But this spring could not exist if it did not have a motion of its own. In order for this to happen, a combination of three things would need to be the exact values: the kinetic energy of the spring, the potential energy needed to overcome gravity and the total time taken to go from the starting point to the end. Now if we take the total time, we find that it takes a great amount of time for a spring to reach its destination! This is because a spring cannot move entirely in one direction for a very long time.

Thus, the only thing that makes a spring move is a change in direction through a force that causes the spring to alter its position from zero to a higher value. If you take a baseball and place it on a table, you will see that there is an enormous change in displacement when the ball is thrown in different directions. A particle that has been carefully chosen so that it has a particular directional distribution, will also exhibit similar dispersion. These particles are referred to as a work flow.

The relationship between the force and the power that cause an object to move can be expressed in terms of a force and power law. Force and power are always equal, only in different units. A force is any kind of forward-directed effort, which pushes an object from a straight line to a curved path. Power, on the other hand, is any kind of backward-directed effort that pushes an object in a curved direction. In simple terms, force equals distance times the power of the force, while power is equal to distance times the force times the square of the acceleration.

The concept of a force or pressure exerted on an object depends on the property that governs the orientation of the object along the x-axis. The formula for the force is actually the derivative of the product of the force acting on the object and the time for the object to move with a constant speed. In the field of mathematics this is called a closed system, where a constant force acts uniformly on an arbitrarily chosen system. This type of law is used to solve problems involving the Law of Conservation of Energy, which states that energy cannot be changed from a point in zero velocity to a point in a greater velocity.
