HELPPPPPPPPP! :(

That's possibe if the object doesn't move.

Like you try to push a heavy box, but it doesn't move at all, then there is no work.

Wait. Is there a difference between the first law of thermodynamics to the conservation of energy?

anonymous · Answer

This is what I found, a definition. "The first law of thermodynamics is the application of the conservation of energy principle."

anonymous · Answer

Ow thankyou. :)
What is the difference between the conservation of mechanical energy and conservation of energy?

No, I think. Any other conservation of energy principles is from the conservation of energy law.
