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??

Work done by the force of gravity on an object depends only vertical displacement.
Work done by gravity is given by the expression, W = mgh
W = mg x 0 = 0 J; here h= 0
Therefore, the work done by gravity on the given object is zero joules.
