Question

prove that work is the dot product of force and displasment​

Answer 1

Explanation:

we represent an applied force by a vector ⇀F and the displacement of an object by a vector ⇀s, then the work done by the force is the dot product of ⇀F and ⇀s. W=⇀F⋅−−⇀PQ=∥⇀F∥∥−−⇀PQ∥cosθ.

Answer 2

Explanation:

Work as the dot product of force & displacement.
