12 mv2 where m stands for mass and v stands for velocity. In classical mechanics the kinetic energy of a non-rotating object of mass m traveling at a speed v is. The formula for kinetic energy is KE.
Total energy of the object mgh.
Perhaps the most difficult aspect of the above equation is the angle theta. With the kinetic energy formula you can estimate how much energy is needed to move an object. The unit of energy is Joule. Mathematically work can be expressed by the following equation.
