Energy & Momentum

What is the formula for calculating momentum?

• m=mv
• p=m/v
• p=v/m
• p=vm

When a bat collides with a baseball, the momentum of the bat

• transfers to the momentum of the ball
• transfers from the momentum of the ball
• does not transfer from the bat to the ball
• does not transfer from the ball to the bat

If two objects collide and stick together, what will happen to their overall momentum?

• momentum will decrease
• momentum will increase
• momentum will stay the same
• none of the above

If 2 objects collide and stick together, what will happen to their velocities?

• velocities will increase
• velocities will decrease
• velocities will stay the same
• none of the above

Which takes more force  to catch, a bowling ball or a ping pong ball?

• bowling ball because it has more momentum
• ping pong ball because it has more momentum
• both require the same amount of force when catching
• bowling ball because it has less momentum

If an action force is a golf club hitting a golf ball, then the reaction force is

• exerted on the golf ball
• exerted on the golf cart
• exerted on the golf club by the golf ball
• exerted by the squirrel that is hiding in the tree
