What is the work done by a person walking on a levelled road with a lod in his head? |
|
Answer» Work done = Force x displacementW = F.s = Fs\xa0cos\xa0θwhere θ is the angle between the direction of force and the direction of displacement of the object. If they are perpendicular to each other θ = 90°. We have cos 90° = 0.ThereforeW = F x s x 0 = 0 Work done = 0 |
