Question

Define work and show that it is the dit product of force and displacement . At what condition work done will be maximum or minimum

​

Answer 1

Answer:

i) Work done is maximum when Force & Displacement are in the same direction as θ = 0, implying W = FS Cos(0) = FS

ii) Work done is minimum when the Force – Displacement are perpendicular to each other.

W = FSCosθ = FSCos90 = FS(0) = Zero
