Parachute

An object in free fall _________________ as it falls

• gets slower

• gets faster

• has a constant speed

Some objects fall slower than others because they have different

• masses

• shape

• colors

Once a parachute reaches terminal velocity, its velocity

• decreases

• stays the same

• increases

To create the most drag, a parachute needs to

• have a small surface area

• be light

• have a lot of surface area

• be heavy

A parachute______________________ would stay in the air the longest

• with a low terminal velocity

• falling at free fall

• that is the lightest

• with a high terminal velocity

Speed and direction (Which vocab word)

• force

• velocity

• acceleration

• free fall

A force that opposes motion through the atmosphere

• equilibrium

• gravity

• air drag

Falling when gravity is the only force acting on an object

• terminal velocity

• acceleration

• free fall

When the forces cancel out (equal and opposite)

• force

• equilibrium

• velocity

• acceleration

When a falling object reaches its fastest speed

• equilibrium

• free fall

• terminal velocity

• air drag
