Question

Why does it take more force to get a resting object to move than it does to keep

a moving object going? (Hint: answer using ideas about microscopic
interactions) *

Answer 1

Objects have a natural tendency to resist change. ... Heavier objects (greater mass) resist change more than lighter objects. Example: Pushing a bicycle or a Cadillac, or stopping them once moving. The more massive the object (more inertia) the harder it is to start or stop.
