When thinking about energy, most people envision work. From how we work to what kind of work we do, most of us have some idea what work is. The only question is how do we work? In this article we will describe the various types of work and explain their definition and relationships. After reading this article you should have a good understanding about the meaning of work.
In Physics, work is energy that is transferred from or to an object during the operation of a particular device. In its most simple form, it can be represented as the relationship between a force and an object’s displacement. Let’s say you want to lift up a piece of paper by hand. In order for this to be accomplished, you must apply a force into the paper from one side to another.
Once the object is lifted, a force acts on the object in the direction that is perpendicular to the direction of motion. The end result of this force acting on the object will be the displacement that is radiated from the point of impact. For example, if you were to shoot a missile from a ship at a certain angle and speed, it would reflect off of the surface of the object being shot. The amount of radiated energy that comes from the object is equal to the magnitude of the angle and speed of the impact. This gives us the concept of work. Work is a function of distance and time.
Momentum is a force that continues to be exerted from a source unless a change in its condition occurs. For example, when a boat is in motion, the amount of horizontal velocity is always done upon the same axis. This also is done upon an object when that object moves in a certain direction. Take an object and move it in a horizontal direction for a while and it will develop a horizontal velocity. This is the product of the time and the magnitude of the force that was applied to it during its motion.
The torque, which is a constant force acting upon an object, can be seen as a combination of a constant force and the work done upon an object. For instance, when two boxes are placed on top of each other and pushed down they will experience a push force, and that force acts upon the top box until it begins to sag. That sag will be a torque, which changes the location of the bottom box and increases its horizontal velocity until it pushes itself up out of the way.
This can also be used to find out the direction of a force. To do this, we need to find the change in the location of an object that accompanies every change in its horizontal or vertical position. Once we have found the direction of this force, we can find the magnitude of this force, which is also known as the effect of the angle on the object. This will give us the direction of the object’s motion, along with its angular momentum, which is the sum of all the components of the object’s momentum that are moving in a given direction at the same time.
