hi sir, for the questions where it asks to find an equation linking v with t for example, is it okay if you use simultaneous equations to solve it? instead of the gradient? cause I still get the same answer
My school just does the chapters in a different order! Lots of schools vary the chapters for various reasons. I think we did vectors after this as we knew it would help when starting mechanics, which we began soon after vectors.
Sir, I really like your videos they are so useful thank you!!
Thank you so much! I am pleased that you're finding them useful!
at 11:08 you also do this in chemistry, gor extroplating data
I’m not sure what you mean by this!
@@BicenMaths I think he meant in chemistry you don't extrapolate data aswell
In these modelling cases, is the dependent variable always on the y-axis?
Yes, independent is always x axis (time is very common), so dependent always y axis
at around 18:50 is there a reason why u didnt multiply the v-4 by 30 as u straight away expanded the bracket
Because I want v as the subject, so I'd have to divide by 30 again afterwards!

Absolutely!
22:34 can you also say that you are extrapolating so its unreliable?
No, as it hasn't asked for us about making a prediction - we should only talk about reliable/unreliable for predictions!
Sir, how comes you go from Chapter 6 to vectors straight away ?
