### Pendulums

Simple Harmonic Motion

Simple Harmonic Motion
• Pendulums and Springs are very similar.
• They repeat the same cycle of motion over and over and over.
• This is called Simple Harmonic Motion
Amplitude = Displacement
• Amplitude: How far away from the equilibrium position

the pendulum

swings.

Period
• Period: The amount of time needed for the pendulum to complete

one full cycle.

A B

From ‘A’ to ‘B’ & back to ‘A’ again

Period
• For a pendulum the formula for Period is:

L= pendulum length

• To find frequency (the number of cycles per second) (Hz):
Practice
• Pg. 379, Practice B
