For your National 5 Assignment you need to produce a report about a relevant area of Physics.
This year we recommend you research and investigate car safety and the affect it has on society.
You could investigate:
- The operation and benefit of seat belts. Since the introduction of seat belts, improvements such as the three-point seat belt, inertia-reel seat belts and pre-tensioning seat belts have been adopted by car manufacturers.
- The operation and benefit of car ‘safety cages’. The ‘safety cage’ provides a safe area for passengers in the event of an accident. It has features which protect passengers from certain injuries.
- The improvement of vehicle braking systems. Antilock braking systems and electronic stability control have improved car braking.
- The improvement of steering wheel design. Steering wheels have been designed to reduce driver injuries during a crash.
- The use of side-bars to reduce injury. These have been developed to protect passengers from side impacts.
- The operation and design of crumple zones. The front and rear parts of cars have been designed to steadily collapse during a collision to reduce injury to the car occupants.
- The design and operation of air bags to reduce injury. Air bags reduce injury to the driver and passengers during collisions.
Do not mix these up! Your aim should relate to your conclusion
