### SHM and p Review

As a pendulum swings back and forth, where does it have maximum kinetic energy?

A. Amplitude position

B. Equilibrium position

C. Somewhere in between

As a horizontal spring system oscillates back and forth, where does it have maximum kinetic energy?

A. Amplitude position

B. Equilibrium position

C. Somewhere in between

• What is the amplitude of the oscillation?

A. 40cm

B. 20cm

C. 10cm

D. Not enough info to know

A pendulum is oscillating with a time period of 1.0s. If the mass on the end of the pendulum is doubled, what is the new time period?

A. 0.5s

B. 1.0s

C. 2.0s

D. Not enough info to know

During an SHM vibration, where will the object have its maximum speed?

A. Amplitude position

B. Equilibrium position

C. Somewhere in between

D. Not enough info to know

During an SHM vibration, where will the force on the object be the greatest?

A. Amplitude position

B. Equilibrium position

C. Somewhere in between

D. Not enough info to know

During an SHM vibration, where will the acceleration of the object be the greatest?

A. Amplitude position

B. Equilibrium position

C. Somewhere in between

An object is vibrating in SHM. If I want to know the speed of the object at a particular position, how do I find that speed?

A. Use one of the trig based equations

B. Apply forces and Newton’s Laws

C. Apply conservation of energy

D. Not enough info to know

An object is vibrating in SHM. If I want to know the position of the object at a particular speed, how do I find that position?

A. Use one of the trig based equations

C. Apply conservation of energy

D. Not enough info to know

An object is vibrating in SHM. If I want to know the speed of the object at a particular time, how do I find that speed?

A. Use one of the trig based equations

B. Apply forces and Newton’s Laws

C. Apply conservation of energy

D. Not enough info to know

A mass of 2kg is attached to a horizontal spring with a spring constant of 0.5N/m.

• What is the time period of the oscillation?

If two objects crash into each other and stick to each other, what can you use to solve that collision?

A. Conservation of energy

B. Conservation of momentum

C. Both Conservation of energy and momentum

D. Newton’s Laws

If two objects crash into each other and they don’t stick together, but they are dented, what can you use to solve that collision?

A. Conservation of energy

B. Conservation of momentum

C. Both Conservation of energy and momentum

D. Newton’s Laws

If two objects crash into each other and they don’t stick together, and there is no denting or heat created, what can you use to solve that collision?

A. Conservation of energy

B. Conservation of momentum

C. Both Conservation of energy and momentum

D. Newton’s Laws

Two identical cars are moving along a straight line towards each other at the same speed. If they have a completely inelastic collision:

A. That means they bounce off each other

B. That means they stick to each other

Two identical cars are moving along a straight line towards each other at the same speed. If they have a completely inelastic collision, what is the speed of the wreckage after the crash?

• Zero
• Double their original speed

Two identical cars are moving towards – this time they are moving perpendicular to each other but still at the same speed. If they have a completely inelastic collision, what direction will the wreckage slide after the crash?
