According to this principle, energy can neither be created, nor can be destroyed. It only changes from one form to another.]]> 2020-07-25 06:48:04 UTC https://padlet.com/andromedanolivia/euxf23qlidfur6fe/wish/662279826 The total mechanical energy, i.e. sum of kinetic and potential energy, remains constant. andromedanolivia https://padlet.com/andromedanolivia/euxf23qlidfur6fe/wish/662279913 2020-07-25 06:48:28 UTC https://padlet.com/andromedanolivia/euxf23qlidfur6fe/wish/662279913 andromedanolivia https://padlet.com/andromedanolivia/euxf23qlidfur6fe/wish/662280365 2020-07-25 06:49:48 UTC https://padlet.com/andromedanolivia/euxf23qlidfur6fe/wish/662280365 andromedanolivia https://padlet.com/andromedanolivia/euxf23qlidfur6fe/wish/662282905 The step by step theoretical verification of conservation of mechanical energy. ]]> 2020-07-25 07:01:37 UTC https://padlet.com/andromedanolivia/euxf23qlidfur6fe/wish/662282905 Conservation of mechanical energy in motion under gravity graph. andromedanolivia https://padlet.com/andromedanolivia/euxf23qlidfur6fe/wish/662283520 2020-07-25 07:05:05 UTC https://padlet.com/andromedanolivia/euxf23qlidfur6fe/wish/662283520 andromedanolivia https://padlet.com/andromedanolivia/euxf23qlidfur6fe/wish/662284944 Q. What is the initial velocity 'u' required to reach a height 'h' ?

Ans: Initial K will be equal to final U, as per conservation of mechanical energy.
Hence: 1/2 mu2   =   mgh
Or u  =   square root of (2gh)
