When is the work done (1) positive (2) negative? Give one example in each case.
Added by Ricardo P.
Step 1
When a force is applied on an object and it moves in the direction of the force, work is said to be done. The work done can be positive, negative, or zero. 1) Positive work: When the force applied on an object is in the same direction as the displacement, the Show more…
