Newton's Laws of Motion/Law of Conservation of Momentum

Two skaters begin at rest. Skater 1 has a smaller mass than Skater 2. After they push off each other,...

• Skater 1 experiences a greater change in momentum
• Skater 2 experiences a greater change in momentum
• Skater 1 has a greater velocity than Skater 2
• Skater 1 experiences a greater force

Which object listed below has the greatest momentum?

• A 0.05 kg object rolling at 0.2 m/s.
• A 0.15 kg object rolling at 2 m/s.
• A 0.15 kg object rolling at 1 m/s
• A 0.4 kg object rolling at 2 m/s.

The Law of Conservation of Momentum states:

• The total momentum before a collision is equal to the total momentum after a collision.

• The total momentum before a collision is greater than the total momentum after a collision.

• The total momentum before a collision is less than the total momentum after a collision.

• The total momentum before a collision is not related to the total momentum after a collision.
