There are always unbalanced forces acting on objects, so objects always have a net force greater than zero

An object at rest will stay at rest and an object in motion will stay in motion unless acted upon by an unbalanced force

A net force acting on an object causes the object to accelerate in the direction of the net force

For every force (action) there is an equal and opposite force (reaction)
