Why do some collisions affect objects differently?

• Because of the physics of force, mass, and velocity

• Because of the size of the objects

• Because of the direction of the collision

• Because of the speed of the objects

How do pool players use physics to their advantage?

• By setting up collisions to make the cue ball stop and the colored ball start moving

• By hitting the balls randomly

• By using a special technique

• By using a different type of ball

What happens when a moving object collides with a still object of the same mass?

• The moving object changes its velocity from motion to rest, while the still object goes from rest to motion with the same velocity

• Both objects stop moving

• Both objects continue moving at the same velocity

• The still object starts moving and the moving object stops

Why does a person with less mass in a bumper car collision move farther than a person with more mass?

• The same amount of force affects the person with less mass more

• The person with less mass applies more force

• The person with more mass applies more force

• The person with less mass has better reflexes

What determines the effects of a collision between objects with different masses?

• The difference in the masses of the objects

• The speed of the objects

• The size of the objects

• The direction of the collision

Why does a bug splatter on a car windshield?

• The bug has much less mass than the car, so the forces have a greater effect on it

• The bug is attracted to the car windshield

• The bug is trying to attack the car

• The bug is trying to escape from the car
