WebFeb 7, 2024 · The issue is that your E ˙ k is a derivative with respect to time, t. U ˙ ≠ − F! F = − ∇ U, which is a spatial derivative, so by the chain rule: U ˙ = d U d t = d U d x d x d t = − F v i.e. the instantenous power. So your equation becomes: E ˙ = 0 = − F v + E ˙ k F = E ˙ k / v, so F = 1 v ( 1 2 m ˙ v 2 + m v v ˙). Which, for m ˙ = 0, gives:
