- Negative work is done when the force and displacement are in opposite directions1234. Examples of negative work include:
- The work done by the buoyant force of water in the drowning of a ship.
- The work done by gravitational force when one climbs a tree.
- The work done by frictional force when pushing a block on a hard surface.
- The work done by gravity on a rocket going perpendicularly upwards.
- Sliding a book across a table.
- Braking a bicycle.
- Squeezing a spring toy.
