Have you ever wondered why your hand hurts when you punch a wall? Well, this is because the wall “punches” back with the same amount of strength in the exact opposite direction. This is a direct example of Newton’s third law of motion. As a mathematician and scientist, Sir Isaac Newton explored the laws of physics and perfected Galileo’s original idea of motion. His life spanned from 1642 to 1727. Through these years, he developed his three laws of motion, the third of which, states that every action has an equal and opposite reaction. This means that whatever amount of force “Object A” exerts on “Object B”, “Object B” will exert the same amount of force back on “Object A”. |
