Features that increase the safety of a car
Newton's Second Law of Motion
Newton's Second Law of Motion states that the force acting on an object is equal to the mass of that object times it's acceleration. This means that if a car crashes, the impact will be affected by the acceleration and mass of the car.
How do mass/velocity effect the momentum and level of injury?
This means that the faster it moves and the heavier it is, the more momentum it has. If the car has more momentum, injuries are going to be worse.
ABS brakes prevent the wheels from locking in an accident which means that uncontrolled skidding can be avoided. ABS brakes allow the wheels of a vehicle to maintain contact with the road surface when braking.
The differences between safety features
- Air Bags
- Seat Belts
- Crash Barriers
- Crumple Zones
Whereas, these are designed to prevent accidents:
- ABS Brakes
- Escape Lanes
- Knowledge of Braking Distance
