Does a rock have mass

Answer 1

All matter, including rocks and their constituents, can be a source of energy. If a rock drops from an altitude, as would a meteorite, it is imbued with "kinetic energy," just like a bullet from a firearm.

A rock may also contain minerals that after they are extracted may yield chemical elements that could yield "thermodynamic energy" as part of chemical reactions.

A rock may also contain atoms that could be used in fission or fusion processes that could produce the type of thermonuclear and fusion energy that occurs in atomic explosions and in the Sun, respectively.

Answer 2

Yes. If it's part of Earth's matter it contains energy, as heat, at least.

Then, if you were to give it a push that made it move, it would have kenetic (mechanical) energy as well. Then the extra energy, from the push, would be transferred through friction to its surroundings, and it would come to a stop, radiate, as electromagnetic wave energy, any excess energy into its environment, and finally return to its original energy state or level.

Answer 3

-- it releases energy when it's dropped (which had to be put into it by lifting it);

-- it releases energy when it cools (which had to be put into it by heating it);

-- just laying there, it doesn't give, take, or use energy.

Answer 4

No. If you want to lift, roll, heat, or break a rock, then you need energy.
