Question

"Energy is neither created nor destroyed but can be changed from one form to another"Now,imagine an object at 10m height from ground, so it has potential energy, if earth disappears suddenly what will happen to its energy?

Answer 1

The scenario is not allowed by Physics.

Explanation:

The website

https://en.wikipedia.org/wiki/Conservation_of_mass

says that "The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time." So if your scenario involves the violation of that Physical Law, why not violate the one about energy being destroyed?

I hope this helps,
