Force causes acceleration.
This acceleration, as well as the force, is governed by Newton's three laws of Motion. The specific forces involved are gravity, weight, Normal force, friction, and tension. I. Newtonian Mechanics Force causes a change in velocity, or acceleration . Newton's Laws Inertia - An object at rest remains at rest, an object in motion remains in motion when there is no force acting upon it. The sum of all forces acting on an object equals its mass times acceleration.
