• Energy lost in a collision

• Energy from air resistance

How does mass affect the force of a collision?

• Less mass means more force

• More mass means less force

• Mass has no effect on force

• More mass means more force

What is the effect of friction during a collision?

• Increases kinetic energy

• Decreases kinetic energy

• Has no effect

• Increases potential energy

How does an increase in speed affect kinetic energy?

• Decreases kinetic energy

• Increases kinetic energy

• Has no effect
