• Terminal Velocity

• Inertia

• Friction

What is the friction-like force that opposes the motion of objects that move through the air?

• Air Resistance

• Gravity

• Weight

• Field

What is the maximum speed an object will reach when falling through a substance?

• Terminal Velocity

• Free Fall

• Inertia

• Friction

If no external forces act on a group of objects, their total momentum does not change. This is known as:

• Law of conservation of momentum

• Free Fall

• Terminal Velocity

• Air Resistance
