Obtain an expression fot K.E of a body moving uniformly?

1.	Obtain an expression fot K.E of a body moving uniformly?
Answer» We know thatv^2 = u^2 + 2aSv= final velocityu= initial velocitya= acceleration due to gravityS = displacementS= (v^2 - u^2)÷2aWork done= force * displacementW = F * SF= maW= ma * (v^2 - u^2)÷2aW= 1/2 * m* (v^2-u^2)If u=0 ( body starts from rest)W= 1/2 * m * v^2=Kinetic energy
