Question

Identify and state the type of energy transformation in the following cases
(i) Riding a bicycle
(ii) burning of crackers.
​

Answer 1

Answer:

While riding a bicycle,the muscular energy of the rider gets transferred to heat energy and kinetic energy of the bicycle.Heat energy heats the rider's body.Kinetic energy provides a velocity to the bicycle to move in rotation.The transformation can be shown as:

Muscular energy=kinetic energy+heat energy

During transformation,the total energy remains conserved.

Answer 2

Answer:

(i) Ans: Potential energy into Kinetic energy

(ii) Ans: Chemical energy into sound energy
