Answer the following questions for a mass that is hanging on a spring and oscillating up and down with simple harmonic motion. Note: the oscillation is small enough that the spring stays stretched beyond its rest length the entire time. (top, equillibrium, bottom, top & bottom, or nowhere)
1. Where in the motion is the acceleration zero?
2. Where in the motion is the magnitude of the acceleration a maximum?
3. Where in the motion is the magnitude of the net force on the mass a maximum?
4. Where in the motion is the magnitude of the force from the spring on the mass zero?
5. Where in the motion is the magnitude of the force from the spring on the mass a maximum?
6. Where in the motion is the speed zero?
7. Where in the motion is the magnitude of the net force on the mass zero?
8. Where in the motion is the speed a maximum?
Yes or no for the next two.
1. When the object is at half its amplitude from equilibrium, is its speed half its maximum speed?
2. When the object is at half its amplitude from equilibrium, is the magnitude of its acceleration at half its maximum value?
