Question

How will you find the work done by a variable force? explain briefly​

Answer 1

Assuming the quantity Δx is small, then the force F(x) acting in that duration can be assumed as a constant force. The area enclosed by the rectangle of length equal to the magnitude of force F(x) and width equal to the displacement Δx, gives the work done by the force during that duration.
