Question

why are the vecile provided with the sheet Belt
​

Answer 1

Answer:

Inertia is the reason that people in cars need to wear seat belts. A moving car has inertia, and so do the riders inside it. When the driver applies the brakes, an unbalanced force is applied to the car. Normally, the bottom of the seat applies an unbalanced force—friction—which slows the riders down as the car slows.

Answer 2

All the cars are provided with seat belts to prevent accidents. The job of the seat belts is to hold the passenger in place so the passenger is almost part of the car which prevents the passenger from flying forward as the car stops abruptly in the case of a collision.
