Dale replied to the thread Undergrad Capacitor Voltages at t = 0: Zero or Split?.@Baluncore is right. If all of the components are ideal then the resulting system of equations has no solution. This is an “irresistible... -
Dale replied to the thread High School Does acceleration affect impact energy vs constant velocity?.I think my post 24 gets them as far as they need for the simplest example that doesn’t “simplify away” the thing they are interested in...

Dale replied to the thread Simple problem with voltages.It looks like ##V_{AB}=0## to me since they are directly connected by a wire. Is the triangle for ##I## just supposed to represent the...
-
Dale replied to the thread Undergrad The Electric Displacement, ##\mathbf D##.That is just a matter of the choice of units. In Heaviside Lorentz units all three quantities have the same units which is even more...

Robert, I'm sorry to hear of the passing of your father. He and I had quite a few interactions over the years, all positive. He...

Haha.
This is a good example of the principle of conservation of thread momentum, requiring no ongoing impulse from the OP. -

Like.
The OP starts off with reference to constant velocity and constant acceleration. How can he be convinced that those ideas cannot be... -
Dale replied to the thread Paul Hinds has passed.Oh, no! Thank you for letting us know, Robert. Your dad was amazing and I will miss him
-
Good afternoon, This is not Paul, but rather his son Robert. I am very sad to write here that my dad passed away on Saturday...

The OP could clear up the context of the question. It all depends on where the original question arose in his mind. If it came from a...

Dale replied to the thread High School Does acceleration affect impact energy vs constant velocity?.I don’t think that car collisions are central to their question. They mentioned it once after many posts either not specifically about...

Dale replied to the thread High School Does acceleration affect impact energy vs constant velocity?.I don’t think the question is specific to car collisions. It seems to me that the OP just wants the simplest basic principles to use to...
-
Dale replied to the thread High School Does acceleration affect impact energy vs constant velocity?.That can happen momentarily in an elastic collision.
-
Dale replied to the thread High School Does acceleration affect impact energy vs constant velocity?.Yes, elastic collisions are bouncy. I don’t think that is a problem here.

The orange of neon, and the blue of argon/xenon, are fluorescence colors. De-excitation occurs in a sequence of smaller energy steps...
