Driving Home Newton's Laws of Motion 

Automobiles, baseballs, skateboards and bicycles --the world is full of things that are in motion. Centuries ago the British physicist Sir Isaac Newton stated three laws that describe the ways in which things move. These are Newton's three laws of motion: 

The first law:  Unless acted upon by an outside force, a body at rest tends to stay at rest, and a body in motion tends to stay in motion. 

The second law: Acceleration is equal to the net force acting on a body divided by its mass. 

The third law: For every action force there is an equal and opposite reaction force. 

A driver starts her car and steps on the gas pedal. The car gradually accelerates to 50 km/hr. A few minutes later, the driver suddenly slams on the brakes to avoid hitting a box in the road. As the car comes to a stop, the driver's body appears to lurch forward in the seat until it is restrained by the seatbelt.
