1.21 use the idea of momentum to explain safety features

Cars are specifically designed to reduce the force transferred to the driver if a collision were to happen.

The safety features include:

• The crumple zone which is the zone where the engine lies in front of the passenger and driver, collapses during a collision and increases the time for the vehicle to be brought to a halt and therefore reduces the force impacted on the driver.
• The seat belt also allows the passenger to come to a stop over a longer period of time, therefore reducing the force they are subjected to.
