An object is said to be in free fall if it is only under the influence of __________.

• gravity
• inertia
• friction
• projectile motion

The force of friction or drag acts on an object in a direction opposing its motion as it moves through the air.

• air resistance

• motion

• friction

• drag force

There is an acceleration when there is a change in ____________.

• speed
• time
• direction
• velocity

Displacement

• scalar

• vector

In free fall, which object - the truck or the paper - will hit the ground first when both drop at the height and the same time?

• The paper will hit the ground first
• The truck will hit the ground first
• The truck and paper will never hit the ground
• Both the truck and the paper will hit the ground at the same time.

Statement 1: In a vacuum, all objects in free fall accelerate at the same rate, regardless of mass.

Statement 2: An object is said to be in free fall if it is only under the influence of gravitational force.

• Both statements are true.
• An object is said to be in free fall if it is only under the influence of magnetic force.
• Objects in free fall accelerate at different rates based on mass.
• Both statements are false.
