an object thrown at a centre angle to the ground moves in a covered Parth and holds that to the ground the initial and the final points of the path of the object Bhai on the same horizontal line what is the work done by the force of gravity on the object

work done on the object while the object goes up by the gravity force
= - m g h negative
work done while the object falls down
= m g h positive
Total work done = 0. = change between initial and final PE energies..
(also the KE initial and final in vertical direction are same)
