7.2 Kinetic Energy and the Work-Energy Theorem - OpenStax

WebThe kinetic energy of a moving object equals one-half the product of its mass and the square of its velocity. Since the mass of an object can never be zero, the square of velocity makes the answer positive. Therefore, kinetic energy can never be negative. Kinetic energy is usually represented by the symbol E K or the abbreviation K.E.
