Question

why do we use seatbelt in cars according to laws of motion

Answer 1

Due to the law of inertia, the objects tend to stay in the same state of motion as they were before the change in motion, as in the case of the car, when we apply brakes suddenly, the car stops but the driver tends to be in motion and if the seatbelts would not be there, the driver would be thrown out of the car.

Answer 2

seatbelts are used to prevent accident.

because of inertia of motion , rest and direction
