There are actually three laws of motion, not "lows". These laws were first described by Sir Isaac Newton in his book *Principia Mathematica* in 1687, and they are fundamental to understanding how objects move. Here they are:

1. Newton's First Law of Motion (Inertia): An object at rest stays at rest and an object in motion stays in motion at a constant velocity unless acted upon by an unbalanced force. This means that objects resist changes in their motion. For example, a book sitting on a table will stay there until you pick it up and move it.

2. Newton's Second Law of Motion (Acceleration): The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This means that the more force you apply to an object, the faster it will accelerate. Also, the heavier the object, the slower it will accelerate for a given force.

3. Newton's Third Law of Motion (Action-Reaction): For every action, there is an equal and opposite reaction. This means that when you push on an object, the object pushes back on you with the same force. For example, when you jump up, you push down on the ground, and the ground pushes back up on you with an equal and opposite force, propelling you upward.

These three laws are essential for understanding the motion of everything in the universe, from planets to atoms.
