Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A car’s seatbelts are needed to
A
keep the forces on the passengers balanced.
B
exert a force that changes the forward motion of passengers.
C
increase the passenger’s inertia.
D
keep all forces from acting on the passengers.
Explanation: 

Detailed explanation-1: -The correct answer is to make our forward motion slower. A safety seat belt in a car exerts a force on our body to make our forward motion slower. When we travel in a moving car, our body remains in a state of rest with respect to the seat.

Detailed explanation-2: -Seat belts are designed to handle a sudden jolt of 1, 000 lbs of force.

Detailed explanation-3: -As per Newton’s first law of motion, when a car abruptly stops or crashes, Due to inertia of motion, a person sitting in a moving car may be pushed forward when the car stops abruptly, potentially causing damage. To prevent the above accident, seat belt must be used while driving car.

Detailed explanation-4: -Since objects will stay in motion until acted upon by another force, the seat belt is the force that prevents you from flying through the windshield. Once you crash, the seat belt’s job is then to help spread the stopping force throughout your body to minimize damage.

Detailed explanation-5: -A seat-belt slightly stretches in a collision, thus it can lengthen the time during which the passenger decelerates and greatly reduce the impact force.
