उत्तर
- 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:
- During the transformation, the total energy remains conserved.
- Muscular Energy → Kinetic Energy + Heat Energy
