In daily life, any useful physical or mental effort, such as chores, studying, or professional tasks, is often considered work.

Climbing stairs or a tree involves exerting force against gravity over a vertical distance, meeting the criteria for work in physics.

Work in science involves the application of force to move an object over a distance, transferring energy in the process.

Considering the sign of work allows for the differentiation between forces contributing to motion (positive work) and forces opposing motion (negative work), providing a comprehensive understanding of energy transfer in various physical situations.

In this scenario, the work done is calculated as the negative product of the force and displacement, signifying the reduction in energy or the opposition to the motion of the object.
