Hello, for Q 12, to check wether stokes law applies the velocities OR drag force have to be equal ? So if the velocity or drag force is less than or greater than the given velocity/DF then stokes law doesn’t apply ?

hey, hi i am Abhishek here.... I loved your videos very much and wanted to thank you very much for doing this for us... i also wanted to check with you if are at present conducting any online tuition classes... If so, I would like to join and please let me know the fees structure.... hoping to hear from you as soon as possible....

Hello Sir. I have a doubt. For question 15 (c) what if you were given the distance from the ball to the point of impact on the ramp. Does it change the way you calculate or is it the same.

[nemithapathirana]

hello sir, the horizontal component of velocity is = ucos theta right?

[dewmithwaranasooriya]

Sir could we use another method on question 12 where we can compare both drag due to velocity and U+D=W

[fatimaakter]

My doubt is at 50:52 of the video. Should I always take 9.81 as -9.81 during any motion of projectile?

[Sama-eqdp]

hello sir, for the 11th question I wrote v^2=u^2+2as, and when we rearrange we get v^2/2s=a=g. So i wrote that the student should plot the graph of v^2 against 2s and the gradient gives us g- which will be a straight line. Is this correct?

[jawahirghafoor]

which website did u get the question paper from?? bcz i cnt get it from pearson as my school hasnt provided me with the account that is required to view papers at pearson...
i have my mock exams for unit 1 in a few days.. please reply me soon...

[amnaashraf]

Sir can you explain how to do vector diagrams. There were many questions related to vector diagram(unit 1).
I have got my jan 2021 paper and i will be repeating it. It would be great if you solve 2021 papers i can send it to u

[zainabyasin]

Sir I have a doubt on 15c. Kindly clear
If the ball bounces on the ramp then the vertical distance will not be 0.86 travelled so why do we use this distance to get the time and then use in finding range

[sarujanthangavel]

Tomorrow I have my physics unit 1 exam

[marwinsteiner]

Nice video, can I find a pdf of the mark scheme somewhere? I've checked Physics and Maths Tutor along with PDF coffee and was not able to find it.

[sara]

where can i find the paper along with the marking scheme?

[_alkashat]

May you provide us with the mark scheme and question paper, please?

[sreyashhaque]

Sir can you please answer why in question 6 you referred F as -ma? Please answer sir.

[tabishkhurram]

Your quadratic equation in question 15 gives Math Error in my calculator, just how did you even get 0.55 seconds?
