In this short video, we explain the Perpetual Pendulum — a clever physics model that looks like it swings forever. As the pendulum moves, a connecting bar shifts the center of mass and gives a small push to keep the motion going. It appears endless, but friction and air resistance eventually slow it down.
What you learn in this video: ✔ How a perpetual pendulum works ✔ Why it looks like perpetual motion ✔ Why it eventually stops ✔ Concepts of gravity, oscillation, and energy loss ✔ Center of mass shifting in simple mechanisms
