Is momentum equal to inertia? So, inertia describes an object’s resistance to change in motion (or lack of motion), and momentum describes how much motion it has. Pop quiz answer: Momentum is your force or speed of movement, but inertia is what keeps you going. Is inertia directly proportional to mass? Inertia is a property […]
