The first law of motion, Newton is also known as. "Law of inertia" (Inertia Law) means that the object is to preserve the original, it retains
the second law of motion, Newton's "that" when there is a net force acting on the object size is not zero. To make the acceleration in the same direction as the force that is acting. And the magnitude of the acceleration is proportional to the size of the force. And inversely proportional to the mass of
the third law of motion, Newton's mind with that. "Every action must have a reaction that is the same size and direction is always opposite to each other.
