Dale replied to the thread Graduate Magnetic monopole vs (g-2).I don't see why a dipole moment anomaly would have any bearing on the monopole. Mathematically the various multipole terms are all... -
Dale replied to the thread High School Deriving the "third" kinematic equation using graphs.This one is no less convincing than the others. Indeed as @pbuk said, this is procedurally exactly the same as what you did for the... -

Indeed. If the OP is satisfied that they can "derive" ## v = v_0 + at ## by plotting ## v \ vs \ t ## and observing the slope then how... -
Dale replied to the thread High School Deriving the "third" kinematic equation using graphs.No, he says that it cannot be the one he showed (##v## vs ##t##). He didn't show ##v^2##. So all he needs is that pointer: use ##v^2##. -
Dale replied to the thread High School Deriving the "third" kinematic equation using graphs.And the answer is very clearly yes. Like the other two equations means you can pick which quantities to plot. So plot ##v^2## and... -

Yes, by multipling ##KE = KE_0 + Fs## with ##2/m##. But seriously, since eq (3) can be easily derived from eq (1) and eq (2), what is... -
Dale replied to the thread High School Deriving the "third" kinematic equation using graphs.If you know ##v## then you know ##v^2##, but the reverse is not always true. It is mathematically possible to know ##v^2## without... -
Dale replied to the thread High School Deriving the "third" kinematic equation using graphs.I don't see what the difficulty is. If you can know and plot ##v## then you can know and plot ##v^2##. It isn't even algebra, it is just... -
Dale replied to the thread High School Deriving the "third" kinematic equation using graphs.I had assumed that all the graphs were obtained from experimental values. -

yes, thanks much for this clarification -
Dale replied to the thread Graduate Is Energy conservation among sectors (EM,GR,QM) a principle?.But that is not the only possible answer. Different authors will make different choices and they are all justifiable. -
Dale replied to the thread Undergrad Explanation requested for a relativistic scenario wherein two seemingly valid measurement procedures lead to different results for the same observable.In B's frame A passed the left pole and started its clock a long time before B passed the right pole. So in B's frame the sequence is... -

Just to check: you are aware that events that are simultaneous in one frame are not simultaneous in another? Your wording in the OP lead... -
Dale replied to the thread Undergrad Explanation requested for a relativistic scenario wherein two seemingly valid measurement procedures lead to different results for the same observable.First, don’t use ##v=0.999 c##. It is an annoying value. Use ##v=0.6 c## so that ##\gamma = 1.25##. That is fast enough that...
