Question

Define potential energy write an expression for the potential energy write the si unit of potential energy

Answer 1

heya mate....

potential energy is the energy possessed by the body due to effect of height or position

work =force. distance

force= mass. acceleration

here acceleration is due to gravity (g)

so,, force=m.g

so,, distance here is height (h)

so substituting ....

work =F. S

===>mg. h

work= mgh

in this case the work is stored as potential energy..

actually it's is stored energy due to relative motion of various parts of body.

as it is form of work it's S. I unit is JOULE or kgm^2s^-2

hope it helps u mate ❤
