Question 7
What are the various energy transformations that occur when you are riding a bicycle?

Answer 1

While riding a bicycle, the muscular energy of the rider gets transferred into heat energy and kinetic energy of the bicycle. Heat energy heats the rider's body. Kinetic energy provides a velocity to the bicycle. The transformation can be shown as:
Muscular Energy $\to$Kinetic Energy + Heat Energy
During the transformation, the total energy remains conserved.
