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.
Answer:
Work is the change in energy brought about by a change in velocity.
When the velocity of an object increases, the environment has done work on the object and the energy of that object is increased.
When the velocity of an object decreases, the object has done work on the environment and the energy of the object is decreased.
