Last week we had a snow day (or more accurately, a wind chill day). And on this day several of my friends and I decided to go to the indoor trampoline park Sky Zone. In addition to it being a ton of fun, jumping on trampolines has something to do with physics. You see, when you jump on the trampoline it stretches its springs, making both the force and the elastic potential energy of the spring greater. Also, to find the potential energy due to gravity you multiply the mass of the person by how high they are from the ground and then by g (the acceleration due to gravity), which is 9.81 m/s^2. In short, trampolines are fun, especially when you don't think about physics while jumping on them.
