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 =========================== Hope It helps You. ^_^ |
