WebIn classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2. WebTotal energy. The total energy is the sum of the kinetic and elastic potential energy of a simple harmonic oscillator: E=K+U_s E = K +U s. The total energy of the oscillator is constant in the absence of friction. When one type of energy decreases, the other increases to maintain the same total energy. Figure 3.
