When the angle is 90° we say the work done is zero. Work done =F s cos θ Where θ is the angle between force and displacement. Where cos 90°=0, so the work done will be zero. Example: A man carry the basket in hand and walk, here force is applied by the hand to carry the basket and displacement is the distance the man travel.
