Thanks Julia and glad it helped you understand this great piece of equipment. I hope my other videos help you too. Good luck with your studies!

That's great to hear! So pleased it helped you out. Plenty more videos in the playlist - some may help. Yes it is old - I was learning to do things on KZfaq back then. Still learning! Hope your studies continue to go well.

Pleasure Chetan - so pleased you found it useful. As ever, enjoy your physics and thanks for commenting.

Me too. kleppner text🥵🥵

@@statusworld-zh8gj Hope this has helped with your studies.

Excellent - so pleased it helped with your understanding. Shame you have not seen one in the lab. They are great fun to play with. Thanks for leaving a comment and, as ever, enjoy your physics!

Excellent - so pleased it helped. 'Third World' countries have produced some of our best and most able scientists so don't think of that as a limitation! Your hard work will pay off! Which country were you watching from?

@@AnthonyFrancisJones I'm from Myanmar. Right now political issues in our country made it unsafe for us students to go to school. People are getting shot left and right. Me and many other kids had to learn via online classes but it isnt going so well because our current government cuts off all internet connections at 9pm to avoid people from spreading awareness. Here's a brief summary of what's going on www.bbc.com/news/world-asia-55902070 . Me and many of my friends are protesting as well so we can't really focus on our studies that much so we rely on youtube videos like yours for most of our education. I'm sorry for rambling on about this and thank you again for this video.

@@throwaway1015 I do hope you are OK and that you can continue your studies. It means a massive amount to me that the small work that I do can be of help to those trying to study in your country. Do please look after yourself and your friends and continue your studies whenever you can.

Yes it is interesting to do different shaped tracks, especially with different masses. I have been meaning to do a video on that for a while using cable trunking or curtain track which allows you to bend it to the shape you need easily. Thanks for watching!

Thanks - glad you found it useful.

Thanks - hope you enjoy the others I have made. Thanks for the comment - I really did not feel that this was one of the most interesting ones but of course the physics is!

I found channel this just now..I am seeing your videos ,just saw heat conduction video.

@@physicsiseverything9138 Great - keep going and let me know your thoughts and comments.

Pleasure - glad it helped and you found it useful. Thanks for taking the time to comment.

Thanks - glad you enjoyed it!

Rishad - hope you enjoy the others and more coming soon. Thanks for the comment.

Yes, I did this as a kind of joke homage to some of my previous pupils who seemed to just try anything mathematically to answer a question even if the equations were for an unrelated bit of physics! Well spotted and good luck with your studies and exams.

Hope you found the video useful!

Tough stuff to read! Hope you found the video useful!

@@AnthonyFrancisJones yeah sure. Really wanted to see the device work.

@@ahirdey899 Great - in the UK I think most school age pupils will have seen it but it is clear that even here less and less do as it is quite an expensive bit of apparatus. A lot of kids will have played with an air hockey table (game/toy) too which is and air track in two dimensions!
