Question 1.
Define momentum.
Show hintHide hint
It's often represented by the symbol p.
Question 2.
What is the law of conservation of momentum?
Show hintHide hint
Consider scenarios where the total momentum doesn't change.
3Question 3.
What does conservation of momentum state?
- Total momentum remains constant
- Momentum can double
- Momentum is always zero
Show hintHide hint
Consider momentum changes only within a closed system.
4Question 4.
True or False: Elastic collisions do not conserve kinetic energy.
- True
- False
Show hintHide hint
Recall the definitions of elastic and inelastic collisions.
Question 5.
Calculate the final velocities of two identical pucks on ice (mass 0.5 kg) that collide elastically, where one puck moves at 3 m/s and the other at rest.
Show hintHide hint
Remember energy and momentum conservation equations.
Question 6.
A 10 kg cart moving at 3 m/s collides inelastically with a stationary cart of 5 kg. Determine their combined velocity after the collision.
Show hintHide hint
Apply the concept of total momentum before and after the collision.
