Homework Statement
I have learned that gravitational potential energy's formula is:
GPE = mgh
But I saw other formulas relating to gravitational potential energy:
[itex]\phi[/itex] = -G(m/r)
And then one formula like this:
F = dU(x)/dx
And then there's a formula relating to the CHANGE in gravitational potential energy:
E = m[itex]\Delta[/itex][itex]\phi[/itex]
Similarly, I'm confused with the electric potential energy:
V = (coulomb's constant)(Q/r) What is this? Why is there a voltage symbol?
CHANGE in electric potential energy:
E = QV What is this?
