Question

Which energy changes take place when a pedaling cyclist uses a generator (dynamo) to light his bicycle
lamp?

Answer 1

At the same time when the generator lights up the bicycle lamp the lamp is light up using electrical energy so mechanical energy is also transformed in to electrical energy.

Answer 2

When the pedaling cyclist uses a generator (dynamo) to light his bicycle lamp, the energy change is from mechanical to electrical.

Law of conservation of energy

The law of conservation of energy states that energy can neither be created nor destroyed but can be converted from one form to another.

Thus, we can conclude the following as it relates to energy changes;

• When the pedaling cyclist uses a generator (dynamo) to light his bicycle lamp, the energy change is from mechanical to electrical.
