Objectives
1 To study pendulum motion in a plane for different masses suspended by a string.
2. To study the factors which determine the pendulum period.
3. To determine the acceleration due to gravity.
Questions
1. Summarize which quantities were measured in this experiment, and which of these quantities had the largest errors.
2. Find the length of a pendulum for which T = 1 s.
3. Find the length of a pendulum for which T = 2 s. What is the ratio of lengths for the 2 s and 1 s pendulums?
4. Suppose the pendulum of a grandfather clock expands because of heat. Will the chick lose or gain time?
5. An astronaut wants to test a pendulum clock and takes it on a trip orbiting the earth. What do you expect him to find out?
Additional Questions for Honors Sections
1. A rocket takes off vertically' from Earth with a uniform acceleration of 3g. How would the period of oscillation Of a simple pendulum installed on board change from being at rest on the earth's surface to the situation when the acceleration is 3g?
2. At a very high altitude the rocket's acceleration drops to zero. Will the pendulum's oscillation become faster, slower or the same as on the earth's surface?
3. A grandfather clock with short vertical pendulum is being carried by a maglev train, which accelerates ?or 10 s with a g. The train then coasts for some time, followed by breaking with deceleration a = -g until stopping. Will the clock lose or gain 'time?
4. ;By how much would the trip time on the grandfather clock differ from actual time if its pendulum swings along the direction of the train's motion? Give a quantitative answer.
