Q
What’s a crumple zone?
A
The cars kinetic energy is converted into other forms of energy by the car body as it changes shape
Crumple zones increase the impact time, decreasing the force produced by the change in momentum
1
Q
What four ways do cars improve safety?
A
- Crumple zones
- Side impact bars
- Seat belts
- Air bags
2
Q
What are side impact bars?
A
Strong metal tubes fitted into car door panels. They help direct the kinetic energy of the crash away from the passengers to other areas such as the crumple zones
3
Q
What do seat belts do?
A
They stretch, increasing the time for the wearer to stop. This reduces the forces acting in the chest, so some kinetic energy is absorbed
4
Q
What do air bags do?
A
Slow you down gradually and prevent you from hitting hard surfaces inside the car
