QUESTION:
Problem 6CQ
(Answers to odd numbered Conceptual Questions can be found in the back of the book.)
Give an example of a frictional force doing negative work.
ANSWER:
Step 1 of 2:
A work is determined known as positive, zero, or negative based on the angle between the force and the displacement. If the angle is greater than 90° and less than 270° the work is negative. The frictional force always does a negative work as the angle is 180°.
