WebHope this helps. To prove that Kinetic Energy is ½ mv^2. We already know that Energy w = f x s that is force x displacement. So, ΔK = W = FΔs = maΔs. From the third equation of motion that is v^2 - u^2 = 2aΔs (-1) where. v = final velocity, u = initial velocity, a = acceleration, and Δs denotes change in displacement. WebThis is a result of the law of conservation of energy, which says that, in a closed system, total energy is conserved—that is, it is constant. Using subscripts 1 and 2 to represent initial and final energy, this law is expressed as. K E 1 + P E 1 = K E 2 + P E 2. Either side equals the total mechanical energy.
