Answer:
Explanation:
It is because when the brakes are applied, the lower part of our body comes to rest as it is in contact with the surface of the vehicle but the upper part of our body tends to remain in motion due to inertia of motion.
If the brakes are applied suddenly, the rate of change of momentum will be more. Therefore, we will be thrown forward with a greater force.
Wearing a seat belt reduces the time taken by the body to change its momentum and hence we can prevent ourselves from getting hurt.
