Herman Trivilino replied to the thread What force causes precession?.##\vec{L} = \vec{r} \times \vec{p}## does imply the relationship between the directions of ##\vec{L}## and ##\vec{\omega}##. So the... -
Herman Trivilino replied to the thread What force causes precession?.But even in those cases the direction of ##\vec{\omega}## relative to the direction of ##\vec{L}## is a consequence of the definition... -
Herman Trivilino replied to the thread What force causes precession?.Note these are consequences of the definition of angular momentum: ##\vec{L}=\vec{r} \times \vec{p}##. -
Herman Trivilino replied to the thread High School Calculating an impossible reference frame as my own homework problem.That's a common misuse of the terminology. We refer to a rest frame as a frame of reference in which something is at rest. So the... -
Herman Trivilino replied to the thread What force causes precession?.By spindle "changing" you mean ##\vec{\omega}## of the rotating object changing direction? Then, yes. -
Herman Trivilino replied to the thread What force causes precession?.That follows from the definition of angular momentum. He states "torque due to gravity". So you don't see that a torque by definition... -
Herman Trivilino replied to the thread High School Calculating an impossible reference frame as my own homework problem.What do you mean by enter a reference frame? What are you trying to learn? -
Herman Trivilino replied to the thread High School Uniform thermal expansion of metals.The thing is, without data to support that conclusion we have, well, no data to support it! -
Herman Trivilino reacted to A.T.'s post in the thread High School Uniform thermal expansion of metals with
Like.
Yes, I think the double hole case is a good follow up question to ask after explaining the single hole case, in order to check if the... -
Herman Trivilino replied to the thread High School Uniform thermal expansion of metals.That's because you already have or others have done so for you. My point is that conclusions like that cannot be arrived at by reasoning... -
Herman Trivilino replied to the thread High School Uniform thermal expansion of metals.There is no single reason that would be valid for everyone. You would need to design a question that would probe that issue. You would... -
Herman Trivilino replied to the thread High School Uniform thermal expansion of metals.My point is, they are a distraction. Doesn't matter how deep they are. The distance ##x## will increase. Put two marks on the disk and... -
Herman Trivilino replied to the thread High School Uniform thermal expansion of metals.Every one-dimensional measurement increases by the same ratio. Put two marks anywhere on the disk and the distance between them will... -
Herman Trivilino replied to the thread Graduate How valid is the Block Universe theory?.When I'm doing spacetime calculations I'm using the same math used by block universe proponents, but I'm not thinking of the future as...
