Read each question carefully and provide your best answer. Show all your work for calculation problems.
1. In an elastic collision, which of the following quantities are conserved?
Momentum only
Kinetic energy only
Both momentum and kinetic energy
Neither momentum nor kinetic energy
2. What is the definition of momentum?
Mass times acceleration
Mass times velocity
Force times distance
Kinetic energy divided by time
3. The law of conservation of momentum states that in a closed system, the total momentum before a collision is equal to the total momentum the collision.
4. In an elastic collision, kinetic energy is , meaning no energy is lost to heat or sound.
5. An inelastic collision conserves kinetic energy.
True
False
6. Momentum is a scalar quantity.
True
False
7. A 2 kg ball moving at 5 m/s collides elastically with a stationary 3 kg ball. If the 2 kg ball bounces back at 1 m/s, what is the velocity of the 3 kg ball after the collision?
8. Describe the difference between an elastic collision and an inelastic collision.
