thank you so much, I am so glad i found ur channel. you are teaching me things even my teacher has not taught me. it's nice to see a teacher that is dedicated to not only your students but any student that watches your videos, I hope all your days are forever filled with happiness :)))))
at 2:40, doesnt one second later mean another second added. so if p was moving 9s, then q would have been moving 10s as its one second later? thanks for everything and i hope you can clear this up and help me understand this.
Hi sir, my end of year 12 exams are coming up and I wanted to ask if you know any websites/places where there are questions for each topic(not a lot) that cover the whole topic and then there is a video or answers showing how to solve it if I got stuck. This is because I don’t have much time and would like to go over everything I learnt within a few questions. Thanks.
Hmm not that I know of, although I have all my exam questions arranged in topics in my Google Drive - you can find it in the About section on my channel.
Hi, At 5:20 can you please explain how you knew that the displacement for each particle is the same? Are you saying that the displacements from point A is the same? Also, could you make both t values equal to each other? Thank you so much!
If we let T by the time for particle A to travel, and then B was travelling but started 1 second before A, then the time for B would be T+1 as it would be travelling for the same amount of time as A plus 1 extra second!
Good question! My calculator has the simultaneous equation solver function, so I imagined that u and a were the x and y variables, and treated it as a pair of simultaneous equations!
We need to have some shared values in order to do simultaneous equations, and by having P with both of them, we have the shared initial velocity. We also have shared acceleration too.

What a lovely, kind comment - thank you so much for writing it! Wishing you all the best for your studies - and let me know if I can help in any way!
@@BicenMaths :)) of course!
could you tell us where you got the worksheet from pls? i would like to practice these questions more
😊
The questions are taken from Exercise 9D of the Applied Year 1 Edexcel textbook, and also from Mixed Exercise 9.
For the last question part a why can’t you do QR and PR and equate the final velocity? I tried it and it didn’t get the same answer
Did you add the distances together to get distance PR? You should be able to use your method, it will work if you have all the correct values!

at 2:40, doesnt one second later mean another second added. so if p was moving 9s, then q would have been moving 10s as its one second later? thanks for everything and i hope you can clear this up and help me understand this.
It means that Q has been in motion for one second less, hence my notation. The time for Q is measuring how long it has been moving for!
Yes!
for 3:02 isnt q 1 second later than p? so, shouldnt it be t plus 1???
No because that would mean it had been travelling 1 second longer than P, but it left 1 second after so it’s time is 1 less than p!
Don’t you have to convert km and hours into si units for the last question, or is it okay to leave it how it is? Thankyou
You do usually - but as we didn't need it in the standard units at the end, this was OK to leave.
@BicenMaths OK, thank you very much!

Hi, At 5:20 can you please explain how you knew that the displacement for each particle is the same? Are you saying that the displacements from point A is the same? Also, could you make both t values equal to each other? Thank you so much!
So they have the same displacement as they have both started and ended at the same point, and you could also have equated the t values too!
can you give me a scenario where you add 1 to T instead of subtracting.
If we let T by the time for particle A to travel, and then B was travelling but started 1 second before A, then the time for B would be T+1 as it would be travelling for the same amount of time as A plus 1 extra second!
@@BicenMaths thank you
At 1:20 how is “u” = 3 and not “v”. If it’s been travelling for 1 second, thats not its initial velocity is itv
We’re about to consider its journey after this point, so 3 is its initial velocity for the journey that we are considering.
Hi sir at
16:01 how di you get the values for U and A please !
Good question! My calculator has the simultaneous equation solver function, so I imagined that u and a were the x and y variables, and treated it as a pair of simultaneous equations!
Don’t understand why you chose PQ and PR for the last question, how do you make that decision?
We need to have some shared values in order to do simultaneous equations, and by having P with both of them, we have the shared initial velocity. We also have shared acceleration too.
