| Home: nikhilesh94 | Original Message | Reply | | Subject: Contributed Answer/Explanation to Q. 25 | according to the law of conservation of energy, energy can neither be
created nor destroyed, it can only be converted from one form to
another.therefore the mechanical energy is conserved throughout

energy is conserved. so the total kinetic energy and potential energy(total
mechanical energy) in a body is conserved.therefore the total energy will be
same in the whole stone's trajectory.only the potential energy and kinetic
energy will vary
