Hi,all, problem is:
in Electromagnetism, we introduced a scalar potential psi, such that:
E = - grad Psi
and In Newton's law, there is also a scar potential U, such that:
F= -grad U
My question is, one is the gradient of a scalar field give a field and a force?!
Can anyone help me with understanding this? That would be great, and many thanks in advance!
