 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
While riding in the backseat of a car, a child holds a cup of juice. When the car suddenly stops, the liquid in the cup will
 A flow off to one side of the cup. B flow toward the back of the cup. C flow in the direction the car was moving. D stop as suddenly as the car stops.
Explanation:

Detailed explanation-1: -By Newton’s third law, that car pushes on your car with the same force, but in the opposite direction. This force causes you to slow down.

Detailed explanation-2: -When a car just stops suddenly our lower body sometimes copes up with the motion change. But our upper body tends to remain in the state of motion due to inertia of the body. Thus, it does not cope up with the motion change and hence falls forward while a car stops due to the inertia of the body.

Detailed explanation-3: -EXPLANATION: When a car suddenly starts moving, the people fall back due to the law of inertia of rest or the 1st law of Newton.

Detailed explanation-4: -As your car accelerates forward, the backward sensation you feel is caused by your body’s inertia, not a real backward force like it might feel. This feeling is jsut as strong as the acceleration causing it, but it points in the opposite direction of the acceleration.
