Sir Isaac Newton's three law of motions

In 1686, he presented his three laws of motion in the “Principia Mathematica Philosophiae Naturalis.”

In the first law, an object will not change its motion unless a force acts on it.

In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
