1) if a pendulum clock keeps perfect time at the base of a mountain, will it also keep perfect time when it is moved to the top of the mountain? explain.
2)if a grandfather clock is running slow, how could we adjust the length of the pendulum to correct the time?
3)explain (a) how it is possible for a large force to produce only a small, or even zero, torque, and (b) how it is possible for a small force to produce a large torque.
