Is the following an example of harmonic or linear motion?
 
The moon orbiting the Earth.

• Harmonic
• Linear

In simple harmonic motion, the displacement is maximum when the: 

• acceleration is zero 
• velocity is maximum 
• velocity is zero 
• kinetic energy is maximum 

A mass attached to a spring vibrates back and forth. At the equilibrium position, the

• acceleration reaches a maximum.
• velocity reaches a maximum.
• net force reaches a maximum.
• velocity reaches zero.
