Voltage:
Voltage is the electrical equivalent of mechanical potential. If a person drops a rock from the first storey of a building, the velocity it will reach when dropped will be fairly small. However, if the rock is dropped from the twentieth floor, it will have reached a much greater velocity on reaching the ground. On the twentieth floor the rock had much more potential energy.
The potential energy of an electrical supply is given by its voltage. The greater the voltage of a supply source, the greater its potential to produce a current flow. Thus, a 115 volt supply has 115 times the potential to produce a current flow than a 1 volt supply.
POTENTIAL
If one coulomb of electrons is added to a body and one joule of work has been done, then the body will acquire of potential of - 1 volt. If the electrons had been removed, then the body would have acquired a potential of +1 volt. The unit of potential is the volt.
consider a star orbitining in the sperically graviational potential Y=(Vc)2 ln(r/r0). a)use conservation of energy and angular momentum to obtain equation for dr/dt and d(teta)/dt

WHAT IS THE MEAN OF HEAT
A 12 Volt battery is associated across a parallel combination of two capacitors C1 and C2. The capacitance of C2 is double that of C2.
A block of mass m is tied to a cord of length L that is pivoted at the center of a frictionless table. A second block of mass m is tied to the ?rst block also on a cord of length L
