Conventions for work and energy are not going correct in this situation [closed]
Let us consider 2 objects A and B.
The initial PE of the objects be U(A)=10J and U(B)=0J. Let F be the force exerted by A on B. Suppose W be the work done by force F. Due to this the PE of both the ...

Is my derivation of the potential energy formula $m*g*h$ correct?
I've just wondered where the formula $E_{pot} = mgh$ you learn at school comes from so I've tried to work it out - is my reasoning correct?
The change in energy is given by
$$\Delta E=\int_{e}^{e+h}G\...

Why have we assume that the there should be no acceleration in deriving the Electrostatic potential energy
In the NCERT textbook grade 12, it is mentioned before deriving the work done in moving a charge $q$ from point $R$ to $P$ in presence of an electric field at Origin, $O$ by charge $Q$
Two remarks ...

Lennard-Jones potential, distance $r$ for minimum energy
I'm sorry if the question seems stupid. I found (wikipedia) that the Lennard-Jones potential has it's minimum at a distance of
$$r = 2^{\frac{1}{6}}\sigma.$$
If $U(r)_{min} = -\epsilon$
$$U(r) = 4\...
