Conservative Forces It takes work to lift an object under the influence of the Earth's gravitational force. This increases the gravitational potential energy of the object. Lowering the ob- ject releases the gravitational potential energy that was stored when it was lifted. When you studied the gravitational force, you applied the term conservative to it because it allows the recovery of all of the stored energy. You...

A common question in physics, which often arises is the question about whether a friction force, f, does work. If a block is sliding down a rough surface with kinetic coefficient of friction, Mu_k. Carefully reflect on discussions held in class, and then, pick the correct statement about whether the force of friction actually does work on the block, as the block slides down the plane. Select one: a. Work done by friction is equal to zero. b. Work done...
