Calculation History

    What is Work?

    Work, in the context of physics, is defined as the product of force and displacement in the direction of the force. Mathematically, it is expressed as:

    Work (W) = Force (F) × Displacement (d) × cos(θ)


    • W represents the work done.
    • F is the magnitude of the force applied.
    • d is the magnitude of the displacement (the distance traveled).
    • θ is the angle between the direction of the force and the direction of displacement. The cosine of this angle accounts for the component of force that is in the direction of displacement.
