Question

Linda has a cup of coffee sitting in the cup holder in her car. She has to suddenly slam on her brakes and stop. The cup remained in the cup holder, but the coffee splashed everywhere. Newton’s _____ law can best discribe why this happened.

Answer 1

Newton's law of inertia says that an object at rest will stay at rest and an object in motion will stay in motion. The coffee was moving the same speed as the car and continued to do so even after the car itself had stopped.
