Inverse Square Law - Required Practical - A-level Physics

[@victorotene]

I have a feeling this topic is going to come up in paper 3 next week. Edit: Lmao, it did.

[@raz3110]

Victor Otene didn’t this come up on the 2017 paper though, so it’s .unlikely to come up again

[@AbdullahiIdri2001]

@@raz3110 There are only 12 to pick from tbf so a repeat isn't off the cards

[@raz3110]

Victor Otene true but Seeing as theres only been 2 papers made with the new spec & around 8 Un used practicals it’s highly unlikely that they’ll repeat it

[@AbdullahiIdri2001]

@@raz3110 What are the 4 that have been done if it isn't too much trouble?

[@matthewportman4987]

My guess is a capacitor one with reading off the graph

Literally just started this this week, thanks for the upload

[@haifamuhammed3819]

Why it’s necessary that the distance between the source and the detector should be greater than the radius of the detector? Please answer

This is a bit of a different question. I want to become a physics and/or maths teacher like you in the future. Can you tell me how do you manage to explain stuff and keep it interesting at the same time and also tell me if I am being stupid by thinking of becoming a teacher.Because that is what everyone around me thinks, they say I should do something better with my life thats pays more. They say that people only become teachers because they couldn't become anything else. This discourages me alot and I start to doubt myself. Sorry if I became too personal and thank you for making awesome videos.

If I am a good teacher now, I certainly wasn't when I started. I made mistakes (and still do), and it took time for me to understand concepts well enough in my own head that I could then explain them in the same way to my students. In other words, it takes time. These videos were made after 6 years of teaching - and even now, 2 years later, there are things I wish I'd done differently. ---- If you have a philosophical view on life like I do, it can be difficult to find satisfaction in any job, as it might seem futile. But by teaching, you directly benefit young people's lives - if that isn't worthwhile, nothing is. ----- But don't forget, all jobs are equally pointless if all there is to this universe is what we can measure/describe with physics. I truly believe that the only true meaning to be found in this life is in God!

@@ScienceShorts You've benefited the life of one young person that I know of (me). Thank you for your kind words of encouragement and please keep on making more awesome videos.

Hi I really need help with a specific question about inverse square law and can't find any sources anywhere so if anyone can help I'd appreciate. The question is how to show a hypothetical student's measurements are inconsistent with the square law I'm give a cpm for 0.2m 0.5m and 1m with 9013 1395 and 242 respectively. Do I simply say that 0.5 is 2.5 times 0.2 so the cpm at 0.5 should be 1/2.5r² or how do I go about it? I'm clearly lost

[@thundercrosssplitattack2064]

So when you plot count, it is the count per second, right?

[@ScienceShorts]

Usually. Sometimes count per minute if it's not that active.

I like the penne pasta does it have radioactive particles

[@mwanawako382]

are you going to make videos for all 16 practicals?

[@BP-qe4qv]

What specification are your videos for ? Or do you just do general a-level physics that multiple specifications cover?

[@sachinirajapakse6963]

Please could you link the video of you doing the practical in the description because I can't seem to find it :)

[@ScienceShorts]

About that...haven't quite got round to doing it yet!

[@ontheway5792]

Please solve CIE Papers!!!!!

[@JamesWilson-ui1wg]

Thank you sir, if I get my grade in physics it’ll be purely thanks to you 🙏🏼 I also learnt this practical and it came up in paper 3 😌

[@Beth-lw5cu]

wait what is the gradient equal to in this? rapid reply pleaseee im cutting it fine

[@enieni8606]

I think it would just be a constant value

[@richard2088]

Could you please do the AQA physics paper 2 2018 for GCSE please. thanks

[@cleomorris9725]

Is there one for Charles'/Boyle's Law? Thank you :)

[@tamircohen1512]

Just did the diffraction grating practical so not doing this one for a while now but thanks for all your help anyway sir!

[@zubair6449]

voidz ah so you follow the normal textbook so you’ve done particles and radiation then waves and then you are gonna do mechanics right?

[@crazyanimal2211]

oh yeah yeah
