Safety belts protect people in cars in the event of an accident because, according to Newton’s Laws of Motion, when an impact causes the car to suddenly change its motion, -

• the people in the car will continue to move in the same direction and at the same speed as before the impact.
• the speed of the car always increases, giving it greater force since the mass will remain the same.
• the speed of the people always increases, since now they have, not one, but two forces acting on them.
• the car now has a greater overall mass - its own mass plus the mass of the object by which it has been struck.
