Longer
Quicker
Air resistance pushes against falling
objects and __________________.

Spins them
The larger the parachute the ____________
Less air resistance
More surface tension
Less drag
More drag

Gravity pushing against moving objects
Normal force pushing against moving objects
The more streamlined an object is, the...
More air resistance
Less air resistance

When dropped from the same distance, which will fall to the floor faster?
Look at the pictures of the cars. Which car will have the most air resistance force acting upon it? They will be moving at the same speed.
All will have equal air resistance force.
Which best describes why a falling object will reach its terminal velocity?
Gravity force is equal and opposite air resistance force.
Air resistance force is equal and opposite the freefall velocity.
Gravity force is equal and opposite the object's mass.
The object's mass is equal and opposite the gravity force.
What is a parachute designed to maximize?
Gravity
Air Pressure
Air Resistance
Thrust
What causes objects to fall slowly through the air
Weight
Surface area
The color
Mass
Why are wings on airplanes curved at the top?
To make the air go faster over the top of the wing. This lowers the amount of pressure on the wing.
To make the pressure on top of the wing greater
To make it look cool
That was the only model they had
Complete the sentence.
It is not the difference in gravity that causes objects to fall at different speeds, it’s the difference in the amount of__________________.
Gravity
Mass
Air resistance
