Pendulum theory
1. Where the acceleration is 0 and where the acceleration is highest in a swinging pendulum.
2. Briefly explain in your own words why the pendulum oscillates.
3. Where is the kinetic energy highest? Please explain why that is so.
4. Write the equation for the pendulum's period T. What characteristic(s) of the equipment affect the period?
5. Briefly explain why a pendulum makes a good clock.
