But it's not the only reliable technique. And for a purely kinematic problem it's unnecessarily complicated, which introduces additional... -

Agree.
I hate to look like I really know what I'm talking about, compared to the moderators here. Still, this being a highschool thread, I... -
For any problem? You think it is "wise" to draw a FBD and analyze the forces, just to answer the question below?

Informative.
Hi @physics it is and welcome to Physics Forums. First, please be aware that personal speculations are off limits for discussion here... -
PeroK replied to the thread High School Doubts about Big Bang alternatives.The Big Bang starts from a "hot, dense" state. This is not the science-fiction forum!

PeroK replied to the thread Simple puzzle: bicycle motion.Why is one not appropriate in this case? That's what I used.

PeroK replied to the thread Simple puzzle: bicycle motion.I just looked at this. We have a force of magnitude ##F_1## applied to the left (backwards). This, through the gearing mechanism, also...

No worries at all! I always felt like we were just chatting (and not arguing) and I like to chat about many random topics in math... -
PeroK replied to the thread Undergrad What is the Difference between Maths and Classical Mechanics?.I apologise if I misunderstood what you were saying.

PeroK reacted to Matterwave's post in the thread Undergrad What is the Difference between Maths and Classical Mechanics? with Agree.
Ok. I'm not sure why you are specifying this again to me. Do you think I don't agree with this? Or do you have an issue with axiomatic...
