Question

derive the expression for kinetic energy in a moving object with velocity v and mass m
​

Answer 1

Answer:

Consider a body of mass "m" starts moving from rest. After a time interval "t" and force applied "F" its velocity becomes V.

If initial velocity of the body is Vi = 0 ,final velocity Vf = V and the displacement of body is "d". Then

work = Force × Displacement

change value using 3 equ of motion and F= ma

replace value

then work is defined as kinetic energy so w is replaced by K.E.
