What are the verious energy transformations that occur when you are riding a bicycle ?

Text Solution

Verified by Experts

The chemical energy of food is transformed in our body into muscular energy is muscles. When we pedal a bicycle,the muscular energy of legs is transformed in our body into muscular energy of muscles. When we pedal a bicycle, the muscular energy of legs is transformed into kinetic energy which rotates the pedals. The rotational kinetic energy of pedals is transferred by bicycle chain to rotational kinetic energy of bicycle wheels. Due to this the bicycle wheels move forward. When the bicycle is moving, then the bicycle as well as the person riding the bicycle, both have kinetic energy.
