What you learn in Theory:
The energy associated with the work done by the net force does not disappear after the net force is removed (or becomes zero); it is transformed into the Kinetic Energy of the body. We call this the Work-Energy Theorem.
What you learn in Practice:
If the body's speed increases, then the work done on the body is positive and we say its Kinetic Energy has increased.
