Newton's third law of Motion
The Third Law of Motion indicates that when one object exerts a force on another object, the second object instantaneously exerts a force back on the first object.
Law of universal gravitation
The universal law of gravitation states that every body in the universe attracts every other body with a force F which is directly proportional to the product of their masses and is inversely proportional to the square of the distance between them.
- This law was given by Sir Isaac Newton.
