Question

Define elastic potential energy derive expression of kinetic energy​

Answer 1

Answer:

It is equal to the work done to stretch the spring which depends on the spring constant k and the distance stretched. According to Hooke's law, the force applied to stretch the spring is directly proportional to the amount of stretch. Where, P.E = elastic potential energy and it's expressed in Joule.

Answer 2

Elastic potential energy is energy stored as a result of applying a force to deform an elastic object.

Derivation of K.E.

W=Fs

v^2-u^2= 2as

s=v^2/2a

F=ma, W= ma , v^2/2a

W= K.E. = mv^2 /2

Hence , K.E. = 1/2 mv^2.
