3. How is potential energy related to work done? Potential energy and work done are directly related. When work is done on an object, its potential energy increases. Similarly, when an object's potential energy decreases, it is doing work on its surroundings. ...

Potential energy and work done by a charge are directly related. The work done by a charge is equal to the change in its potential energy. This means that when a charge moves from one point to another in an electric field, its potential energy changes and work is done. ...

Kinetic Energy Energy can exist in many forms: heat, light, nuclear energy, chemical energy (from food or fuel), stored (potential) energy (such as the energy stored in a compressed spring) and so on. Energy can be transferred from one form to another and can be used to create motion....
More energy is used, which means more work is done. That work takes more power, which generates more heat. The potential energy of any given object is a measurement of its potential to do work, create heat and generate power. For this reason, the calculation of an object's potential ...
. In fact, theamount of potential energy a system possesses is equal to the work done on the system. Potential energy also can be transformed into other forms of energy. For example, when a ball is held above the ground and released, the potential energy is transformed into kinetic energy...
