Talk:FHSST Physics/Work and Energy/Energy

On definition of term 'Potential energy' - 'Potential energy is the energy an object has due to its position or state.'

It looks incorrect a bit - internal (thermal, for example) energy is also described by state, but this energy is not potential, obviously.

One more note - may be it's a bad idea to avoid negative numbers - gravitational energy is (actually) always negative.

And, may be the general formula for energy of gravitational interaction energy shuld be added?

$$ E_p=-G\frac{m_1 m_2}{r} $$
