WORK CALCULATOR


Work calculator in physics to find the work done on an object which moves through a distance by a constant force. SI unit for work is newton-meters (N.m) or Joule (J) : 1 J = 1 N.m .

Work is a scalar quantity and it has no direction, but only positive or negative magnitude.

The formula of work is W = Fdcosθ where F is the magnitude of the constant force, d is the magnitude of the displacement of the object and θ is the angle between the directions of the force and the displacement.

Work Calculation Examples:

Example-1: A person pulls a 20-kg box 10 m along a horizontal floor by a constant force FP = 25 N which acts at a 40°angle. The floor exerts a friction force Ffr=10 N.

Determine the work done by FP and Ffr acting on the box, and (b) the net work done on the box.

Solution: The work done by FP is WP = FPdcosθ = (25 N)(10 m)cos40° = 191.5 J.

The work done by the friction force is Wfr = Ffrdcos180° = (10N)(10m)(-1)=-100 J.

Wnet = WP + Wfr = 191.5-100 = 91.5 J
