according to mass-energy equivalent theorem, Regardless of whether the object is at rest or moving, the object of mass m having energy E=mc2.(adsbygoogle = window.adsbygoogle || []).push({});

suppose a ball of mass m is placed on ground, then how much energy this ball have???

Is it equal to E=mc2 ??

now if we place this ball above the ground up to height h, Is this mean all Energy of ball (i.e E=mc2) is converted to potential energy (mgh) ???

if so this ball have so much tremendous energy!!!!

how it can be possible?????
