11th Physics: Work, energy and power

1 / 10

1. Under what condition can a force NOT have associated potential energy?

2 / 10

2. It is well known that a raindrop falls under the influence of the downward gravitational force and the opposing resistive force. The latter is known to be proportional to the speed of the drop but is otherwise undetermined. Consider a drop of mass 1.00 g falling from a height 1.00 km. It hits the ground with a speed of 50.0 m s-1. What is the work done by the gravitational force?

3 / 10

3. A cyclist comes to a skidding stop in 10 m. During this process, the force on the cycle due to the road is 200 N and is directly opposed to the motion. How much work does the road do on the cycle?

4 / 10

4. Does the force of friction have an associated potential energy?
