Newton`s Three Laws of Motion
... Unbalanced forces (the net force) cause objects to accelerate. Fnet = ma The greater the net force on a mass, the greater the acceleration. The greater the mass of an object, the less the acceleration. An unbalanced force is also called a net force. The net force is the sum of the forces acting on a ...
