Question

Product of force and displacement in the direction of force. Give one word answer.​

Answer 1

Explanation:

Q1.   A force of 7N as on an object. The displacement is, say 8 m, in the direction of the force. Let us take it that the force acts on the object through the displacement. Wtm is the work done in this case?

                    

Ans. F=7N

        s = 8 m

        W = F × s

        = 7 N × 8 m

        W = 56J

        ∴ Work done is 56 J.

Answer 2

Explanation:

work done is equal to product of force and displacement .
