An object thrown at a certain angle to the ground moves in a curved path and fall back to the ground. The initial and the final points of the path of the object lie on the same horizontal line. What is the work done by the force of gravity on the object.
No, work is done by the object or the force of gravity. The reason is that the displacement of the object is taking place in the horizontal direction, whereas, the force of gravity is acting downwards in the vertical direction.
