In Chapter 7, the work-kinetic energy theorem, , was introduced. This equation states that work done on a system appears as a change in kinetic energy. It is a special-case equation, valid if there are no changes in any other type of energy such as potential or internal. Give two or three examples in which work is done on a system but the change in energy of the system is not a change in kinetic energy.

1. Can work be done on a system if there is no motion?

A) Yes, if an outside force is provided B) Yes, since motion is only relative C) No, since a system which is not moving has no energy D) No, because of the way work is defined 

2. The quantity 1/2 mv 2 is

 A) the power supplied to the object by the force  B) the work done on the object by the force  C) the kinetic energy of the object. D) the potential energy of the object.

3. If you push twice as hard against a stationary brick wall, the amount of work you do 

A) doubles. B) is cut in half  C) remains constant but non-zero  D) remains constant at zero 

4. If the net work done on an object is positive, then the object's kinetic energy 

A) increases. B) decreases  C) remains the same D) is zero
