An object 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?

Explanation

The work done by the force of gravity on the object is zero. This is because the force of gravity acts vertically in the downward direction and the displacement of the object is in the horizontal direction.
