Question

5 example of negative work done

Answer 1

1 The work done by Gravitational force when we climb on a tree
2 the work done by frictional force of air when a ball is falling downwards.
3 the work done the buoyant force when a coin is sinking
please mark as brilliant answer

Answer 2

Answer:

The work done is the measure of force applied on a body which acquires a certain displacement. As force and displacement both are a vector quantity, their product, work is also a vector quantity.

Thereby, the work done can be a negative work done. A negative work done is work done when the force applied and displacement achieved are not in the same direction of motion.

Examples of negative work done are thus as follows –

a. The push of a block on a frictional surface

b. Climbing a tree against the gravitational force

c. Drowning of ship against the water buoyant force

d. Kicking a moving football while in motion

e. The adventure sport of Tug of war while opponents pulling the rope hard.
