Question

Work done by a cody when its centre of gravity moves in horizontal direction]

Answer 1

Answer:

The amount of work done by the force of gravity on the object is zero. This is because the net displacement of the object is in the horizontal direction while the force of gravity acts in the vertical downward direction.Work 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.
