1st Law: during a crash, the car stops immediately, while the passengers continue to move forward. Airbag technology and seat belts combat this. (an object in motion tends to stay in motion)

2nd Law: force= mass x acceleration. Airbags help to reduce to force on a crash victim's skull.

3rd Law: every action has an equal and opposite reaction. A car hits another, and the recipient of the force pushes back.

Answer:

1. 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.

2. 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).

3. For every action there is an equal and opposite re-action.
