Identify the type of work done by the force of gravity on the bucket of water being pulled out of the well
Answers
Answer: Work done is considered positive when the displacement is in the same direction as that of the applied force and negative when the displacement is in the opposite direction of applied force.
(a)Positive
In the given case, force and displacement are in the same direction. Hence, the sign of work done is positive. In this case, the work is done on the bucket.
(b) Negative
In the given case, the direction of force (vertically downward) and displacement (vertically upward) are opposite to each other. Hence, the sign of work done is negative.
(c) As force and displacement are in opposite directions, work done is negative.
(d) As force and displacement are in the same direction, work done is positive.
(e) As force and displacement are in opposite directions, work done is negative.
