1. Lesson 10/21 Pendulums Starter Look at the pendulum and describe its motion. Too Easy? What is the time period of a simple pendulum? What is the motion simple pendulum called?

2. Pendulums oscillate (move side to side) • The amplitude is the distance from O to either A or B • Time period is the time for 1 complete cycle of motion. • -Time from A to B B A O The equilibrium point

3. Time period of a pendulum • This will depend on • Length of the pendulum. Time period = 1 /frequency Complete the summary questions.
