drag force and terminal velocity

When the air resistance or drag is equal and opposite to the weight of the object you would call this

• 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 force that is opposite to motion of a falling object is_____

• equilibrium

• gravity

• air drag

• Normal force

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

Which force of the following will help a skydiver to reach terminal velocity?

• Force of gravity

• Normal force

• Drag force of air

A 900 N skydiver reached a constant terminal velocity while in the air, what is the drag force (air resistance)?

• 450N up

• 450N down

• 900N up

• 900N down

Which one is a contact force?

• air drag

• weight

Just after she jumps out of the plane (before the parachute opens). The net force will be

• zero

• upward

• downward
