### 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

- During a full cycle, a pendulum bob travels a total distance of 40cm.
- 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

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 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

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 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 a huge pendulum is built with a string that is 9.8m long, what is its time period?

- 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

C. Need more info to know what that means

- 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?
- Need more info to know
- 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?
- Need more info to know
- At 45o

- A car moving North has a completely inelastic collision with a car moving West. If the wreckage moves more North than West we know:
- The North car was moving faster
- The North car had more mass
- The North car had more momentum

- Ball A rolls into a stationary Ball B. After the collision, Ball A is going the opposite direction. Which ball has more mass?
- Ball A
- Ball B
- Need more info to know for sure
