• The pull of gravity on an object

• Resistance to motion

How does gravity affect motion?

• It accelerates objects downward

• It causes objects to stop

• It increases friction

• It decreases velocity

What is friction?

• A force that accelerates motion

• A force that resists motion

• A force that only affects stationary objects

• A non-existent force

What is acceleration?

• The rate of change in velocity

• A force that opposes motion

• A decrease in speed

• The total distance traveled

How does mass affect acceleration?

• More mass means more acceleration

• More mass means less acceleration

• Mass doesn’t affect acceleration

• Less mass means less acceleration
