In physics, kinetic energy is the energy of an object in motion. Kinetic energy, KKK, measured in joules (\text{J})(J)left parenthesis, start text, J, end text, right parenthesis, is calculated using the formula K =\dfrac{1}{2}mv^2K= 2
1

mv
2
K, equals, start fraction, 1, divided by, 2, end fraction, m, v, squared, where mmm is the mass of the object, measured in kilograms (\text{kg})(kg)left parenthesis, start text, k, g, end text, right parenthesis, and vvv is the velocity of the object, measured in meters per second (\text{m}/\text{s})(m/s)left parenthesis, start text, m, end text, slash, start text, s, end text, right parenthesis.
