Mechanical kinetic energy formula
WebApr 7, 2024 · P.E = mgh = 0.4×10×10=40J. Now, halfway down, the kinetic energy of the body can be calculated using the law of conservation of mechanical energy. At this position, the kinetic energy gained will be equal to the potential energy lost which will be half of 40J. Thus, the kinetic energy of the object will be K.E = P.E/2 = 40/2 = 20J. WebDec 28, 2024 · Note that the photon does not have mass, so we can’t simply use the mechanical kinetic energy equation to determine the associated kinetic energy. Instead, the energy associated with electromagnetic radiation is given by E = hf, where f is frequency and h is Planck’s constant 6.626 × 10-34 Js.
