Insights Quaternions in Projectile Motion

AI Thread Summary
The discussion focuses on the application of quaternions in analyzing projectile motion, highlighting their derivation and alternative methods. Two worked examples illustrate the practical use of quaternions, including one that addresses projectile range on a slope. The approval process for using AAPT materials was described as straightforward, with AAPT representatives being supportive of the renewed interest in archived articles. Overall, the thread emphasizes the effectiveness of quaternions in simplifying complex motion calculations. The insights provided contribute to a deeper understanding of both quaternions and projectile motion.

Nicely written! Great job!

How hard was it to get the AAPT to approve your use of their material?
 
Thanks for your kind comment. AAPT (or their representatives) were very helpful - I think they were happy for a long-archived article in AJP to get some renewed attention. Certainly there was something of a process to be followed (as you would expect) but at the end of the day the permission granted was very generous in extent.

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Inclined treadmills and Galilean Invariance'

This has been discussed many times on PF, and will likely come up again, so the video might come handy.
