Imagine you are riding in a car when the driver has to brake suddenly. Your body is thrown forward and stopped by the safety belt. Which of the following best explains why this happens?
A
Inertia
B
Speed
C
Acceleration
D
Balanced forces
Explanation: 

Detailed explanation-1: -Whenever the driver applies the brake, the rider’s body will still be in action, but the car will stop. The rider’s relative motion will be slow against the rider’s preexisting velocity. Thus, the inertia will push you forward.

Detailed explanation-2: -Effects of Inertia You and the car have inertia. If the car comes to a sudden stop, your body tends to keep moving forward. When the car starts moving again, your body tends to stay at rest. You move forward because the car seat exerts an unbalanced force on your body.

Detailed explanation-3: -When a fast moving vehicle is stopped suddenly the person sitting in it tend to fall forward. This is due to inertia of motion. Inertia of motion: If a body is in a state of uniform motion, it continues to remain in the same state unless an external force act on it.

Detailed explanation-4: -(b) Inertia of motion: If brakes are applied all of a sudden in a moving car, passengers automatically lean forward.

Detailed explanation-5: -Slamming on the brakes can throw a person’s body forward and jerk it at odd angles, which can cause serious injuries to the driver and the passengers inside the vehicle. Head, neck, and even brain injuries can result.
