Unit 5: Forces & Momentum
When objects interact, like forces are exchanged and
momentum is transferred.
Name
◊ Each student will accurately predict the motion of objects following an
interaction.
Date

Block A slides along a frictionless surface at 1m/s.
Block B is stationary.
The two blocks will collide.
Use this example for questions 1-5.
1. During the collision, what will be the direction of the net force on block B?
a)
b)
c) no net force will be exerted on block B
2. During the collision, what will be the direction of the net force on block A?
a)
b)
c) no net force will be exerted on block A
3. During the collision, the force exerted by block A on block B is...
a) greater than the force exerted by block B on A.
b) less than the force exerted by block B and A.
c) the same as the force exerted by block B on A.
4. During the collision, the acceleration experienced by block A is...
a) greater than the acceleration experienced by block B.
b) less than the acceleration experienced by block B.
c) the same as the acceleration experienced by block B.
5. Predict the velocity of block B after the collision.
