Physics

1.Draw a diagram of a swinging pendulum and indicate the point(s) where the

acceleration is 0 and where the acceleration is highest. Also indicate where the speed

is 0 and maximum.

2. Run the pendulum simulation at http://www.walter-fendt.de/ph11e/pendulum.htm and briefly explain why the pendulum oscillates.

3. According to the simulation, where is the kinetic energy highest? Please explain why

that is so given your answers to the previous questions.

4. Write the equation for the pendulumís period T. What characteristic(s) of the

equipment do(es) the period depend on? Verify your result; change the variables in

the simulation and note any change (or not) in the oscillation period.

5. Briefly explain why a pendulum makes a good clock.
