Question

define law and conservation of energy with 2 examples​

Answer 1

Answer:

The law of conservation of energy says that energy is neither created nor destroyed. When people use energy, it doesn't disappear. Energy changes from one form of energy into another form of energy.

For example :- 1) In a torch, the chemical energy of the batteries is converted into electrical energy, which is converted into light and heat energy.

2) In a loudspeaker, electrical energy is converted into sound energy.
