<em>if the object has 0 potential energy it means it is on ground ..
<u>explanation :
</u>to measure potential energy we take ground as a reference point but when object is placed on reference point i.e ground then height is 0..
as potential energy = mgh .. here h becomes 0 so potential energy is 0 joules..</em>
