Question

write the law of conservation of energy.Find potential energy if 5 kg mass is at 5 meter height.

Answer 1

energy can neither be formed nor destroyed it can only change from one form to another- law of conservation of energy

Answer 2

According to law of conservation of energy,energy can neither be created nor destroyed.It can only be transformed from one form to another.
Ex-Sunlight can be used in solar panel etc. as solar energy.
Potential energy=m*g*h
                           =5*10*5
                            =250 Joule.Ans.
