Newton’s Three Laws of Gravity
1. The Inertial Law: A body at rest or in motion at constant velocity in a straight line remains in that state of rest or motion unless acted upon by an outside force.
2. The Force Law: The rate of change in a body’s velocity (its acceleration) from an applied force is in the same direction as the force and proportional to it, but is inversely proportional to its mass.
3. The Reaction Law: For every applied force, a force of equal size, but opposite direction arises.
