Assignment - Physics Work Conceptual simple work

1. Give an example of something we think of as work in everyday circumstances that is not work in the scientific sense. Is energy transferred or changed in form in your example? If so, explain how this is accomplished without doing work.

2. Give an example of a situation in which there is a force and a displacement, but the force does no work. Explain why it does no work.

3. Describe a situation in which a force is exerted for a long time but does no work. Explain.

4. A body moves in a circle at constant speed. Does the centripetal force that accelerates the body do any work? Explain.

5. Suppose you throw a ball upward and catch it when it returns at the same height. How much work does the gravitational force do on the ball over its entire trip?

6. Work done on a system puts energy into it. Work done by a system removes energy from it. Give an example for each statement.

7. Two marbles of masses m and 2m are dropped from a height h. Compare their kinetic energies when they reach the ground.

8. Compare the work required to accelerate a car of mass 2000 kg from 30.0 to 40.0 km/h with that required for an acceleration from 50.0 to 60.0 km/h.

9. Suppose you are jogging at constant velocity. Are you doing any work on the environment and vice versa?

10. Two forces act to double the speed of a particle, initially moving with kinetic energy of 1 J. One of the forces does 4 J of work. How much work does the other force do?
