Linear Air Track - F-J's Physics - Video 39

[@Julia-kf5kv]

thank you so much sir! my school doesn’t do many experiments so it was great to see you demonstrate them even if it wasn’t a hands-on experience!

[@AnthonyFrancisJones]

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!

[@athullya.v.l.2769]

I'm also here after reading K&K 's introduction to mechanics... I hope you'll post more useful experiments , sir ❤Thank you ❤ Edit : I didn't even notice this video is 4 yrs old 😮👏🏻

[@AnthonyFrancisJones]

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 KZbin back then. Still learning! Hope your studies continue to go well.

[@chetanrathaur2407]

Came here as I was not able to understand it in "Introduction to Mechanics" by Kleppner. Thank you so much for the video.

[@AnthonyFrancisJones]

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

[@statusworld-zh8gj]

Me too. kleppner text🥵🥵

[@AnthonyFrancisJones]

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

Thanks. Unfortunately no videos online with accurately measured elastic collisions with unequal masses. Make light gate timers, buy them, use two video cameras? Probably beyond GCSE.

[@AnthonyFrancisJones]

Yes, we do have all the gear to do this and light gates should be used for GCSE experiments especially 'The Effect of Force on Acceleration.' I am embarrassed to admit that even with plenty of light gates, timers and systems that would plug into laptops I always steered away from that a bit. I hated the 'tech' not working and preferred that the result could be 'seen' rather than 'measured with a black box'. I wanted students to predict what would happen visibly and really understand the mechanics of what was happening rather than just seeing 'times' change. I think I was out on a limb there as all my colleagues were experts at using light gates!

[@stevecummins324]

I'd be very interested to see motion on a track which has a slope with point heights of y=(ax)^2 ? I'm thinking might produce some interesting results when masses that are rectangular, have their orientation wrt track changed. same mass, same slope, but different accelerations?

[@AnthonyFrancisJones]

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!

[@soorajk7296]

Really helpful. When I read my theory part of linear air track after watching this vedio it became more understandable

[@AnthonyFrancisJones]

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!

[@throwaway1015]

Thanks so much, sir! I was really confused by the diagrams in my textbook and since I'm from a 3rd world country, I couldn't really experience it first hand. Your video made it easy to understand!

[@AnthonyFrancisJones]

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?

[@throwaway1015]

@@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.

[@AnthonyFrancisJones]

@@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.

[@physicsiseverything9138]

Make more videos!!! Love this video

[@AnthonyFrancisJones]

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!

[@physicsiseverything9138]

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

[@AnthonyFrancisJones]

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

[@goldensiddiqui]

Thank-you so much sir

[@AnthonyFrancisJones]

Thanks - glad you found it useful.

[@peggi3561]

Very well explained...❤️

[@AnthonyFrancisJones]

Thanks - glad you enjoyed it!

[@asna.v.t1445]

You made it easy ☺️ Thank you sir

[@AnthonyFrancisJones]

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

[@rgarnet2677]

Expect more physics related videos..

[@AnthonyFrancisJones]

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

0:11 Me during my exam.

[@AnthonyFrancisJones]

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.

[@ahirdey899]

Who else here after reading Kleppner?

[@AnthonyFrancisJones]

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

[@ahirdey899]

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

[@AnthonyFrancisJones]

@@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!
