Work Calculator

Work is the energy transferred when a force causes an object to move. It's calculated as W = F × d, where the force must be applied in the direction of motion. Work is measured in Joules (J).

Yes! Work is negative when the force opposes the direction of motion. For example, friction does negative work by slowing down a moving object. Positive work adds energy, negative work removes energy.

No. If an object doesn't move (displacement = 0), no work is done, regardless of how much force is applied. For example, pushing against a wall does no work if the wall doesn't move.

Work is the process of transferring energy. Energy is the capacity to do work. When you do work on an object, you transfer energy to it. They're measured in the same unit (Joules).

For the basic formula W = F × d, yes. For variable forces, you need calculus (integration). The simple formula works for constant forces applied in a straight line.

Use the component of force in the direction of motion: W = F × d × cos(θ). Only the force component parallel to the displacement does work. Perpendicular forces do no work.
