Potential and Kinetic Energy
... The law of Conservation of Energy states that energy cannot be __created__ or ___destroyed___, but can only __change form______. Therefore, as potential energy __decreases___, it is not gone, but transformed into moving energy called ___kinetic___ energy. Think of the energy as money. If potential e ...

What is an electric field?
... Consider the task of moving a positive test charge within a uniform electric field from location A to location B as shown in the diagram below. In moving the charge against the electric field from location A to location B, work will have to be done on the charge by an external force. The work done o ...

... Law of Conservation of Energy and Efficiency 1. Kate plugs in her hair dryer. The device uses 12,000 J of energy. 8,500J is converted to motion to move the inner fan, 500J is converted to sound, and 1,500 is converted to thermal energy. Does this support the law of conservation of energy? Explain. ...
