To determine
The reason due to which the body of a person moves toward the front of the car when the brakes apply suddenly.

Answer to Problem 1CQ

The body of a person moves toward the front of the car when the brakes apply suddenly is due to the inertia of motion.

Explanation of Solution

Inertia is the property of any object to resist the change its state of motion or state.

The Newton’s first law of motion states that an object remains in its state of rest or motion until or unless a external force applied on it. This is also known as the law of inertia.

When the brakes of the car apply suddenly then the body of person wants to remain in the state of motion due to the inertia. Thus the person moves toward the front of the car.

Conclusion:

Therefore, the body of a person moves toward the front of the car when the brakes apply suddenly is due to the inertia of motion.
