It gives the formula for the kinetic energy theorem between states 1 and 2. In the mechanics of deformable solids, the internal energy only depends on the strain state. By using the analogy with the work of external forces, the chapter defines the strain energy. Then in order to determine ...

How is the Relativistic Work-kinetic Energy Theorem derived? The theorem is derived from the laws of motion and the principles of relativity. It involves integrating the force acting on an object over a distance to find the work done, and then using the relativistic expression for kinetic energ...

Here the work-energy theorem can be used, because we have just calculated the net work,Wnet, and the initial kinetic energy,12mv2012mv02. These calculations allow us to find the final kinetic energy,12mv212mv2, and thus the final speedv. ...
