WebE = E 0 + m v 0 Δ v. or in terms of the change in energy: Δ E = m v Δ v. There are a few different ways to proceed from here, one is to multiply by Δ t / Δ t = 1 and rewrite as: Δ E = m ( Δ v Δ t) ( Δ t) ⋅ v. Now recognizing from Newton's 2nd law that. m Δ v Δ t = Δ ( m v) Δ t = Δ p Δ t = F. We have that. WebUnlike velocity, acceleration, force, and momentum, the kinetic energy of an object is completely described by magnitude alone. Like work and potential energy, the standard metric unit of measurement for kinetic energy is the Joule. As might be implied by the above equation, 1 Joule is equivalent to 1 kg* (m/s)^2. 1 Joule = 1 kg • m2/s2.
