Newtons first law of motion correct answers (law of inertia) An object at rest will stay at rest unless a force acts upon it. An object in motion will not change it's velocity unless a force acts upon it. Newtons second law of motion correct answers Acceleration is produced when a force acts on a mass. The greater the mass the greater the amount of force needed. (F=M*A) Newtons third law of motion correct answers For every action there is an equal and opposite reaction. Newtons law of ...
