Question

examples for negative work and positive work ​

Answer 1

Answer:

Negative work. If the force and the displacement are in opposite directions, then the work is said to be negative. For example if a ball is thrown in upwards direction, its displacement would be in upwards direction but the force due to earth's gravity is in the downward direction.

Explanation:

Negative work ex..

In such case the displacement is opposite to the direction of force that is dominated. And the work done by the force is negative, Take an example of a pulley fetching water from the well. ... Gravity does negative work in this case while tension does positive work..

positive work ex...

If the force applied to do the work features a component that has the same direction of displacement of the object, the force is said to be doing positive work. Some examples of positive work are: # Work done because of the force exerted to lift a block.
