Answer:
The work-energy theorem says the following
Wnet = ΔE
Wnet = Ef - Ei
Therefore, the net work is equal to the difference between the final energy and the initial energy.
It can be rewritten as:
Ei + Wnet = Ef
So, it looks like the equation for the conservation of energy (Ei = Ef) but it adds the term for the net work (Wnet) on the left side of the equation.
