Question 9

Periodic Motion

Answer 9

Anything that happens over and over at a regular time interval. Ex.) clapping, sun coming up

Question 10

Simple Harmonic Motion

Answer 10

A special type of periodic motion that a.) has to have an equilibrium point and b.) has to have a linear restoring force

Question 11

Linear Restoring Force

Answer 11

As the distance away from the equilibrium grows the force grows with it proportionately

Question 12
