Energy - Types of Energy
... Electrical devices use the fact that as electrons flow along a conductor, friction between the electrons and the conductor’s atoms occurs. Whenever you get friction you get heat, so the movement of electricity generates heat energy. Some devices that are designed to produce heat energy are: ...

... 86. The ball is moving in a circle of radius l h . If the ball is to complete the circle with the string just going slack at the top of the circle, the force of gravity must supply the centripetal force at the top of the circle. This tells the critical (slowest) speed for the ball to have at t ...
