An objects thrown at a certain angle to the ground moves in a curved path and falls 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.

Solution

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.
