What is energy conservation?
What do we mean by conservation of mechanical energy? State the condition when it holds.
we learnt that the total energy during a physical or chemical process is conserved. Why, then, do we hear so much about the energy crisis? If energy can neither be created nor destroyed, we should have no worries! We should be able to perform endless activities without thinking about energy resources!
Explain how energy is necessary in our life and explain what are the steps we should follow to save and conserve energy ?
If energy is conserved i.e. it is neither created nor destroyed, why do we need to conserve energy?
