What is the work-energy theorem, and why is it important? The work-energy theorem states that the total work done by all of the forces on the object is equal to the change in kinetic energy of the object. This theorem is important because it allows us to predict the direction, speed,...
Work done on an object transfers energy to the object. The translational kinetic energy of an object of mass m moving at speed v is KE=12mv2KE=12mv2. The work-energy theorem states that the net work Wnet on a system changes its kinetic energy, Wnet=12mv2−12mv20Wnet=12mv2−12mv...

The work-energy theorem, also called the principle of work, and kinetic energy states that the total work done by calculating the sum of all the forces acting on a particle is equal to the change in the kinetic energy of that particle. The theorem can be extended to rigid bodies by descr...

5. Work energy theorem This theorem states that if some work ($W$) is done by the body then the kinetic energy($K.E.$) of the body also increases by the same amount. Work done = increase in K.E. of the body 6. Potential energy of a spring The potential energy ($P.E.$) of...
One of the most basic principles relating work and energy is the work-energy theorem. This theorem states that the work done on an object is equal to the change in its kinetic energy. In other words, if a force acts on an object to move it a certain distance, the work done by that...
