Sweet, thank you for that explanation, in my book, I can follow it up to the dsin(theta) part, but I don't understand how to explain the part with the n in words, and you've just done that, thanks a lot buddy!
i know im kinda late to show this, and wouldve been more useful earlier on, but this website has all the questions interms of topics of PHYA2, meaning you can work on your weaknesses, so i suggest for everyone who is struggling with a specific topic, to have a go at their topic stated in the website tomorrow !!

looking through all the 6 markers, the majority was materials and waves and one on energy (Ep and Ek) so i think this time around something on energy/ mechanics will come up weirdly. im expecting the unexpected tbh.
For the count the squares under the line trick, what's the the general method of part sqaures. Do we consider them as halves or something?
Hey, What is up? m8, you know that jan 13 paper? I did it today. The question 2c, you were right. Since the velocity is same, there is no increase in ke so it must be only heat and sound due to friction. since, EK=1/2xMxV^2.
