Question

write an expression for the work done when force is acting in an object in direction of displacment​

Answer 1

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.
