"No forces" and "zero net force" are in fact the same thing, since we are considering a single particle. If you have a particle at...

Yes, but the OP's issue, as I understand it, is that "no forces" and "zero net force" are not the same.

Hmmm... That's a tough question. To investigate on your own you need a college-level introductory physics background before you can dig...

Yes. Thanks all. Your comments resolved the ambiguity about internal energy and potential energy.

You need at least two objects (usually modeled as particles) interacting with each other (via a conservative force) to have potential...

Potential energy of one object is indeed zero. I agree with that but don't understand what you mean by an origin or by "another point"...

Have you considered a button on the home page, like the search button for example, that does the same thing as the link. Making the link...

Well, sure. After all, statistical physics underpins all of thermodynamics. (It just occurred to me that that could be an answer to the...

I've had pretty good luck with them. Not so with the 18650's though. They seem to have declined in quality in the last few years. I...

OK, I guess I'm only buying name brand batteries now. Lumafield makes CT scanners for industrial engineering and production testing...

Conservation of energy was in serious danger of being abandoned when experiments by Curie seemed to show that radium salts were creating...

When Newton wrote about action and reaction he was referring to forces. It was the 1680's. The concept of energy, if it even existed at...

The table doesn't move relative to the floor in any frame.

Up to a point - depending on the brain. It actually happened in the lighthouse. What I saw was much easier to contemplate than a...

In the 19th century researchers unified two different different types of phenomena, mechanical interactions and thermal interactions...
