WORk -In physics, a force is said to do work if, when acting, there is a displacement of the point of application in the direction of the force.
Negative work occurs when the force acting on an object is opposite in direction to the displacement. So when you lower the book, you are applying an upwards force to it, but its displacement is downwards.
