Which of the following is not correct? Select one: a. Work occurs when a force is applied to an object through so that the object is moved some distance. b. If a force is applied to an object but there is no displacement, then no work is done. c. The work done by gravity is always negative. d. The work done by a constant force is the product of the magnitudes of the parallel component of the force and the...

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...
