• terminal velocity

• gravitational weight

• flux capacitor

• rotational inertia

An object in free fall _________________ as it falls

• gets slower

• gets faster

• has a constant speed

To create the most air drag (resistance) , a parachute needs to

• have a small surface area

• be light

• have a lot of surface area

• be heavy

A falling object will slow down only when ______

• Force of gravity becomes greater than drag force

• normal force becomes greater than gravity

• drag force of air becomes more than gravity

• gravity = drag force of air
