Question 1.
Define momentum.
Show hintHide hint
Think about how fast and heavy something is.
Question 2.
What type of collision conserves kinetic energy?
Show hintHide hint
Remember the balls that bounce perfectly.
3Question 3.
In an elastic collision, what is conserved?
- Momentum and Energy
- Only Momentum
- Only Energy
Show hintHide hint
Think of the ball that doesn't lose energy.
4Question 4.
True or False: Inelastic collisions involve kinetic energy loss.
- True
- False
Show hintHide hint
Remember what happens during a car crash.
Question 5.
A 5 kg ball moving at 10 m/s collides elastically with a 3 kg ball at rest. What is their final velocity after the collision?
Show hintHide hint
Set up two equations: one for momentum and one for kinetic energy.
Question 6.
In a perfectly inelastic collision, a 2 kg object moving at 12 m/s collides with a 3 kg object at rest. What is their joint velocity after collision?
Show hintHide hint
Use the formula for conservation of momentum.
