WebThe kinetic energy of a particle is one-half the product of the particle’s mass m and the square of its speed v: K = 1 2mv2. K = 1 2 m v 2. We then extend this definition to any system of particles by adding up the kinetic energies of all the constituent particles: K = ∑ 1 2mv2. K = ∑ 1 2 m v 2. WebIn classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared.
