Bike, Suspension Spring
This is a spring off a mountain bike near Jester. It is not used in the traditional form of energy but used to "rob" kinetic energy and store and release it very quickly. This spring is a key part of the suspension as the force of gravity and the impacts its causes with a bike can damage or break a bike but the spring is compressed to take some of that energy, absorbing shock, and release it shortly after the impact so as to absorb the blow of an impact. Essentially, it works through impulse as well as it absorbs and releases the force over some (short) period of time.
