A tricycle is a machine used by children to move from place to place. It is made up of simple machines and parts like a frame, wheels, pedals, and handlebars. A child provides energy by pedaling the pedals, which act as levers and turn the front wheel. As the front wheel turns, it pulls the rest of the tricycle and the back wheels along with it. The handlebars also act as levers, allowing the child to change the tricycle's direction by applying force at the pivot point where the handlebars connect to the frame and front axle.
