The Intuitive Physics of Circular Motion (Centripetal Force)

Why does a swinging stone pull so violently against your hand? We are taught to memorize the centripetal acceleration formula $a = v^2/r$ in physics class, but we are rarely shown the beautiful, elegant truth behind it. In 1659, decades before Newton published his laws of motion, a Dutch scientist named Christiaan Huygens cracked the code of circular motion using nothing but basic high-school geometry. In this video, we are going to freeze time and re-discover this universal law from scratch. By looking at a turning object not as a smooth curve, but as a continuous "fall" away from a straight line, a hidden geometric secret inside the circle reveals itself. You don’t need to be a physics genius to understand this, by the end of this video, you'll realize it's a piece of logic you could have figured out yourself.
