Derivation of law of conservation of energy.

Energy conservation

  • -4

Law of conservation of energy states that energy cant be created and cant be destroyed. but it can only transform from its one form to another.

Potential energy + kinetic energy = constant

mgh + 1/2 mv2 = constant

  • 0

agree wid above

  • -3

Energy cant be created nor be destroye only it can be transformed..

Law of conservation of energy (during a free fall )

Let a object be 'm' , lay on point 'a' and is lifted to pt 'h' and stopped at pt 'b'

therefore work done on the body is mgh.

as the body is at rest at 'b'

Kinetic energy at 'b' = 0

Potential energy at 'b' =mgh

Therefore total energy at 'b' =mgh +0

                                                 =mgh

 

the answer is really very long 

if u want it just inform me I'll give.
