I read somewhere online that according to Coulomb's law, in the context of an atom, the potential energy of an electron is proportional to the distance (squared) between the positive and negative charges, this however doesn't show up in the actual eq F = kq1q2/r^2 I thought about it in terms of...

I was thinking about the concept of the ground being the arbitrary zero potential point for gravitational potential energy and considered that since gravity is the attractive force between two objects that there would be no potential energy if an object's center of mass were somehow situated...

Okay that makes sense to me; thank you for your input.

Ok, so it doesn't really matter if I switch the positive and negative charges and make the negative one that moves...the same potential will result. One thing I read though that I have trouble relating to this negative and positive charge separation view of potential is the following: a...

I just watched a videos explaining electric potential and voltage in terms of gravitational potential. A negative charge was drawn with electric field lines converging into it and then a positive charge placed in the vicinity. The video explained that work was required to overcome the...

Ok so temperature is basically the measure of motion (energy) of an object's particles and when two things are at different temperatures energy is transferred from the higher temp to lower temp object until both at at the same temperature. This energy transferred is called heat and so as a...

The definition for energy is not so simple; units are joules (kg*m^2/s^2) a force is an interaction commonly expressed as a push or a pull with units of Newtons (kg*m/s^2) I can imagine heat pushing molecules thus resulting in increased motion...

I know that energy transfer can be done through a force or through heat but I was thinking about heat energy causing water to boil and move around. I thought why isn't heat considered a force? When there is something hot one can physical perceive heat radiating from the object - it seems...
