Derive the formula for kinetic energy of objects of mass m moving with velocity v

Answer»

HEYA.......!!!!


________________________



We KNOW that CHANGE in kinetic ENERGY is = Work done .


⇒ ΔKE = W


⇒ ΔKE = F*x ( work done = F*x )


⇒ ΔKE = ma*x


Applying equation of motion:


=> v² = u² = 2as ( u = 0 )


a = v²/2x

Put VALUE of a in ( ma )


Kinetic Energy = 1/2mv²
