Even more swing physics



Who didn’t jump off swings when they were younger? Even as little kids, we knew that the best time to jump was when the swing reached it’s greatest height. By doing so, the maximum amount of gravitational potential energy is converted into kinetic energy when the person becomes a projectile. At a higher height, the velocity of the projectile is greater. If one were to jump off a swing at a lower height during its oscillation, the angle of projection would also be smaller. This could possible lead to the person landing underneath the swing, only to be hit in the head when the swing comes back, because it is an example of simple harmonic motion. So, whenever you’re on the playground, remember your physics, and avoid head injuries!
