This form of motion can only occur in outer space or in a vacuum. It is solely dependent on the force of gravity.

• Free Fall Motion

• Centripetal Motion

• Projectile Motion

• None of the Above

Inertia is....

• for every action, there is an equal and opposite reaction
• larger objects take more force to move 
• an object in motion tends to stay in motion unless acted on by an opposite force
• a push that acts in the opposite direction and it slows down.
