The time-average of the specific kinetic energy is equal to e. Kinetic Energy KE ½ M V2 Here M is the mass of the point mass in Kg or rigid body and V is the velocity msec at which it is moving. Vy V sinth - 98t.
K ½ mv 2.
In other words every object around us has kinetic energy. So the kinetic energy at rest should be zero. This relationship is generalized in the work-energy theorem. It is straightforward to show that these three equations sum to the kinetic energy equation given by equation 6 the extra pressure terms vanishing for the incompressible flow assumed here.
