Protection Mechanism:
The purpose of seatbelts is to hold back the occupant in the seat during a car crash. The seatbelt distributes the impacts force over a bigger area of the body meaning that risk of injury is heavily reducing as the force is spread out evenly. The seatbelt also stops the person in the seat from flying foward when the force impacts the car in a car crash as it has a locking mechanism when the occupant is jolted foward at pace.
Physics Principle:
Force and time is clearly used in a seatbelt operation. When a car suddenly stops due to a collision, the force only acts upon the car, however, the occupant's body continues to move at the same speed as no force as acted upon them. Seatbelts are able to make this motion gradually slow down over a longer time. This means that the force applied to the person is reduced and spread out meaning less chances of serious injury.
Protection Mechanism:
Airbags purpose is to, like seatbelts, spread the impact in a car crash to stop any specific part of the occupants body from concentrated impact. They are also able to reduce the risk of the person upper body or head striking the vehicle's interior and therefore stopping major injury or fatalities.
Anti-lock Braking System (ABS) is another safety feature in cars. This feature stops wheels from locking up during hard braking. It does this by rapidly throbbing the brakes, allowing the driver to keep steering control and achieve saftey during emergencies. ABS reduces the risk of skidding, improves stability, and shortens stopping distances on slippery surfaces.
Research five safety features included in vehicles.
Explain how these safety features protect its occupants.
Apply the Physics principle between force and time to ONE safety feature in the way it reduces injury to its occupants.
The purpose of crumple zones is to absorb impact energy during a car cras so the energy and force from the crash is expanded across the less important parts of the car rather than where the people are. The strong outer part of the car comes with front and back crumple zones that assist the car in absorbing the impact and force so passngers are not injured.
Electronic stability control helps drivers keep control during skids or loss of control. It does this by applying individual brakes and reducing engine power to certain wheels wheels.
