Name each law: For every action there is an equal and opposite reaction F=ma, an object acted upon by a net force will accelerate in the direction of the force, and that the acceleration equals that net force divided by the object's mass An object at rest stays at rest and an object in motion, stays in motion unless acted upon by an unbalanced force
