Simple Harmonic Motion

Question 1

What is simple Harmonic motion

Answer 1

When an object vibrates back and forth. Typically a pendulum or object on a spring

Question 2

What does the position time graph look like

Answer 2

A sine graph that creates the function x=Acos(2pi/t)

Question 3

What are the two condition for simple harmonic motion

Answer 3

1. Has to have a restoring force
2. The restoring force has to be proportional to the distance for equilibrium.

Question 4
