WebJun 28, 2015 · Is this the correct way to find the derivative of kinetic energy? $$ K=\frac{1}{2}m v^2 \\ $$ So: $$ \frac{dK}{dt} = \frac{1}{2} \left(\frac{dm}{dt} v^2 + 2mv … WebHow do you calculate derivatives? To calculate derivatives start by identifying the different components (i.e. multipliers and divisors), derive each component separately, carefully set the rule formula, and simplify. If you are dealing with compound functions, use the chain rule. Is there a calculator for derivatives? WebNow, as aΔt = Δv we have ΔE ≈ mvΔv But where does the factor 1 2 come in? From basic calculus: Δ(v2) = (v + Δv)2 − v2 = 2vΔv + (Δv)2 ≈ 2vΔv which yields ΔE ≈ 1 2mΔ(v2) = Δ(1 2mv2) and thus E ≈ 1 2mv2 + const If we go from finite to infinitesimal time intervals, the equations become exact and we no longer need to assume a constant force. green window company
