Question

Derive the expression for the work done when the displacement is in the direction of force​

Answer 1

Answer:

W=F.d

W=FdCos(theta)

Explanation:

since displacement is in the direction of force so angle between them is zero now:

cos0=1

so work done is maximum

now:

expression would be:

W=Fdcos0

W=Fd

hope so it would help you in complete understanding.
