Question

Derive the formula to measure the work done when a body mover at an angle to the direction of force

Answer 1

let there be a force applied on the body ie F

along some path r which makes an angle x with the positive x axis

as work done is given by the product of force and displacement

then the work done is given be

W=F.s

=Frcosx

W=F*r*cosx

r=distance moved
