Explain the work energy theorem including the direction energy moves and how it relates to positive and negative work

Answer and Explanation:

The working-energy theorem defines work as the energy change brought on by the velocity change. The environment has acted on the object and it increases the energy of the object. When an object's velocity decreases, the object has worked on the world, and the object's energy decreases.

Unless the displacement is in the reverse direction and the force applied, then the work performed is negative. If the displacement is in the same direction and the force applied, then the work performed is positive.

catya your not at all which answer i've seen you do this on another question!
