WebWork is done whenever a force or a component of a force results in a displacement. No component of the force is acting in the direction of motion when the book is moved horizontally with a constant velocity. The force and the displacement are independent. No work is done by the hand on the book. WebWork is done whenever a force or a component of a force results in a displacement. No component of the force is acting in the direction of motion when the book is moved … WebAnswer (1 of 3): There is one fallacy in both earlier answers. You have to define the force or force field which is doing the work. In pushing a load on ground, you are doing work against friction. In lifting a load, you are putting in work against … essentia health spooner wi audiology
