What is the main difference between negative terminal and ground terminal of voltage source?
The ground terminal in a circuit is just a reference for absolute potentials at different nodes. It really does not matter if you call the potential at _any_ node as ground. So, if you wish you can call the positive terminal of a voltage source as ground. All the circuit analysis will still hold good. Defining a ground terminal will in no way affect the physical properties of the circuit.
The negative (or positive) terminal of a voltage source is relevant in the following sense. When you connect the two terminals of the voltage source to two nodes of the circuit, then there is a change in the physical properties of the circuit - potential & current. You are adding potential between the two nodes. So the negative terminal along with the positive terminal tells us the stepping up of the potential in that mesh.
TL,D? negative terminal of a VS is fixed w.r.t to the VS. The ground can be any node (for convenience) in the ckt
