When is the pendulum at maximum velocity

• At its lowest point

• At its highest point

• It moves at a constant velocity

• It is at rest

When is a mass-spring system in simple harmonic motion?

• Always

• Until the spring is stretched to the point it becomes deformed

• Never

• Only at small amplitudes

When does the mass move at maximum velocity in a mass-spring system?

• At equilibrium

• At the farthest point from the equilibrium

• At its hightest point

• At its lowest point

What are the two requirements for a simple harmonic oscillator?

• The object vibrates about the equilibrium point and the restoring force is proportional to the displacement

• The object moves left to right and the restoring force is proportional to the displacement

• The object vibrates about the equilibrium and the restoring force is greater than the displacement

• The object moves left to right and the restoring force is greater than the displacement
