Master the Concept of Work in Physics

Work in physics is the energy transferred to or from an object via the application of force along a displacement.

For a constant force aligned with the direction of motion, work equals the product of the force strength and the distance traveled.

The work done by a force is considered positive if it has a component in the direction of the displacement at the point of application.
