I finally made an index of all my videos on youtube. You need flounder no longer. Try http://docphysicsindex.com, where I've sorted the videos by chapter and put them into a reasonable structural order.
does the centripetal force change if the center of rotation is already rotating around another center ? Example: (if sun gravity affecting earth is 9.8m/s^2 are we going to be weightless at night and ejected to the sun during the day? )
Hello!! Could you please please quickly (before May 1, and at the very max before May 18, I have an extremely important entrance exam on May 22 and this topic, while I sort of get it, I don't really really get it.) do some videos on variable mass systems and rocket propulsion, preferably with a few problems?
Thank you so much for your videos. They've helped me a lot over the past two years of school.
+STSfoxface L That's a negative. This is a busy time for me, too! Thanks for watching, though. Sorry. Advice: keep working problems and then try to teach it to someone else.
Do you think that uploading on : ...( surface tension / angle of contact for fluids on a surface/ excess pressure inside soap bubble due to surf. tension )...would be good idea for you ??
I'd have to do some research, but it would be fun to investigate. I'm sure you'll be better off finding it elsewhere if you want to learn about it before 2016, though...
+Randy Travis I'll defer to others for that. I love DIY electronics, but I am a learner in that field, not an expert. Let me know what you find, though. I'm beefing up my electronics labs this year.
I'm a second year science teacher, and your videos are so invaluable for my physics class! I teach all three core sciences (bio/chem/physics) so having a resource like this has been a god send! Thank you!! :)
Impact is not well defined. Sounds like a force to me, though. Impulse is force integrated over time (or force times time if they're still hiding calculus from you).
