3 Laws Of Motion

Inertia: An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

The man was placed in the car put force was applied to the car so the man that was in motion moved because the force was applied.

Acceleration: Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

Everyone knows that heavier objects require more force to move the same distance as lighter objects.

Action And Reaction: For every action there is an equal and opposite re-action.
