 2nd September 2017, 01:04 AM #1 Kumar Penultimate Amazing     Join Date: Oct 2003 Posts: 12,243 Potential Energy--Dynamics? Hello, Many time, Potential Energy(PE) confuses me. Very simple question: Whether PE is potential to work or potential to return to origional(natural, rest, grounded..) position? I mean for example, a pendulum at rest(its natural position) should have maximum potential to move on both sides whereas on moving, it has potential to come back to rest(its natural position). Many such examples can be noticed on this link: http://examples.yourdictionary.com/e...al-energy.html Best wishes. __________________ To try reach to Absolute & Final(A&F) is my honest desire.

No, homeopathy still doesn't work. __________________ Who is General Failure? And why is he reading my hard drive?

It's the potential to move to a state of lower potential energy, and this can be used to do work. Quote: I mean for example, a pendulum at rest(its natural position) should have maximum potential to move on both sides whereas on moving, it has potential to come back to rest(its natural position). The lowest point is not the "natural position", it is merely the point at which its potential energy is at minimum. Its kinetic energy at this point will be at maximum. All positions in which the pendulum can be are equally "natural", and an ideal pendulum, on which friction didn't act, would continue to swing indefinitely. And the "natural" condition of things is not to be at rest; it is to have constant velocity unless a force acts on them.

No but just at rest. At this position, what is its PE, maximum, minimum or nil? A new question will be: Whether PE is dependent of its acquired energy? Say, In moving pendulum, it will itself come to rest position without applying any force but outside force will be needed to move it.

No, if a freely hanging pendulum is at rest it will be in its state of minimum potential energy. Potential energy isn't "potential to move when force is applied", it is energy that the pendulum has because of its position relative to the direction of gravity. A swinging pendulum has maximum potential energy, and minimum kinetic energy, at the top of its swing, and minimum potential energy, and maximum kinetic energy, at the bottom. Quote: Do you mean, a moving penulum is its natural possition and at rest not? No, I mean that things have constant velocity unless a force acts on them.

What part of "the pendulum is at its maximum gravitational potential energy" do you not understand? Quote: A new question will be: Whether PE is dependent of its acquired energy? Say, In moving pendulum, it will itself come to rest position without applying any force but outside force will be needed to move it. The point at which a swinging pendulum is not moving is at the top of its swing. At this point its potential energy is at maximum, and its kinetic energy is zero. From this position it will return to its "rest position" because of the force that gravity exerts on it. But it will not stay there, because at that point tge potential energy will have been converted to kinetic energy. Quote: How it can be relevant to PE?

Kumar, read this: Quote: If you cut the pendulum string/chain/whatever it will fall. Thus it still has PE. That's the very first reply to this thread. You evidently didn't understand it. The pendulum, as a pendulum, has its lowest potential energy at the bottom of its swing. That doesn't mean that it has no potential energy at all. But for the gravitational potential energy it has at that point to come into play it must cease to be a pendulum, and become simply a free-moving mass. And no, there are no states below ground state. __________________ "You got to use your brain." - McKinley Morganfield "The poor mystic homeopaths feel like petted house-cats thrown at high flood on the breaking ice." - Leon Trotsky

Kumar, a pendulum will eventually come to rest because its potential and kinetic energy will be lost to friction. It will come to rest at the lowest point of its swing because at that point there is no force that can move it in a direction in which it can move. It is nothing to do with whether that position is any more "natural" than any other position, or whether movement is somehow "wrong". __________________ "You got to use your brain." - McKinley Morganfield "The poor mystic homeopaths feel like petted house-cats thrown at high flood on the breaking ice." - Leon Trotsky
