How do bicycles work? The science behind this ''simple'' machine.

Bicycles turn energy created by our bodies into kinetic energy. Kinetic energy is " a property of a moving object or particle and depends not only on its motion but also on its mass. " If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy.
