Final answer:
The correct answer is option B~ Prevent injuriesThe main goal of airbags is to prevent injuries by deploying upon impact and extending the time over which force acts on car occupants, thus reducing the force and lessening injuries.
Step-by-step explanation:
. Airbags are safety features designed to minimize serious injuries to passengers during a collision. When there is a sudden stop, airbags deploy and extend the time over which the net force acts on the occupants, thereby reducing the force experienced by them. This concept is known as impulse, which is the product of the net force and the time over which it acts. The change in momentum during a crash is constant, with or without an airbag; it's the force that's greatly reduced with the airbag's intervention. Therefore, air bags do not prevent accidents or replace the need for seat belts but work together with seat belts to offer additional protection.
Airbags are designed to prevent injuries to vehicle occupants in the event of a collision. When a car experiences a sudden stop or impact, airbags quickly inflate to create a cushioning effect and reduce the force exerted on the passengers. This helps to minimize the risk of serious injuries such as head trauma and chest injuries.
When the force of impact acts over a longer time period, it decreases the force experienced by the occupants. The dashboard padding, as well as the ability of the car to crumple during a collision, also contribute to increasing the time over which the force acts and reducing the force on the passengers.
