If you push a 900N refrigerator with the same force as you lift a 40N dumbbell, the dumbbell will move faster. which of Newton’s laws is this an example of? Explain how you know please. i know it's not the 3rd law.

  1. Tom

    Newton's second law. The heavier object has more mass, and acceleration is direc tly proportional to force and inversely proportional to mass.
