Derive the formula to calculate kinetic energy of an object according

1.	Derive the formula to calculate kinetic energy of an object according to 3 marks
Answer» We know that work=F.s =ma s (=v2- u2/2a) so ma×v2- u2/2a then 1/2 m (v2- u2) (u=0) then k.e = 1/2mv2 W= m × a × s = m × a × v2- u2/2a = 1/2 m (v2 -u2)Consider u= 0 thenW= 1/2 mv2 Hence the kinetic energy possessed by an object of mass m moving with velocity v is :K.E = 1/2mv2
