 When work is done **by** exactly one force, the above is formula is used. However, when calculating for work **on** an object, or **total work**, the sum of all forces ($\Sigma F$) should be used instead of $F$.
 
-The **work-energy theorem** states that work is also equal to the difference in kinetic energy of an object.
+The **work-energy theorem** states that the **net work on** an object is also equal to the difference in kinetic energy of an object.
