First Law - when an object is at rest, it tend to stay at rest. if an object is in motion, it stays in motion with the same speed, unless an external force is applied to it(like gravity and friction).
Second Law - The force applied in the object is directly related to the acceleration applied to the object and the mass of the object. F = ma (force is equal to mass times acceleration)
Third Law - for every action (force) there is an equal and opposite reaction (a pairing opposing force).
