Question

Quizplus · Accepted Answer

The milk carton has inertia, which is the resistance of any physical object to any change in its velocity. This includes changes to the object's speed or direction of motion. When the paper is jerked quickly, the inertia of the milk carton causes it to remain in place rather than moving with the paper.
