- Make sure you can deal with these!
Here is my choice of the hardest questions you could get on Friday. Skip to the end for the hardest one...
#gcse #physics #revision #aqa #paper2 #examquestions
0:00 How to prepare
1:02 Force vector diagrams (HT)
6:03 Conservation of Momentum calc (SEP)
12:50 Radiation comparison
17:52 Orbits calculation
Physics grind is on now 😎
Icl this teacher is the only way ima get 65+ on this paper (aqa higher combined)
Time to lock in🙏
Cool, thanks a lot and wish me luck! Very useful
Good luck!
Cheers sir
for first question you can use pythagoras which is in my opinion easier as you dont need to convert to centimetres
Correct, but only to check your answer. for GCSE you need to draw the scale diagram
You can use trig for the angle as well
how would you tackle a calculation? I always understand the formulas but never understand which ones I need to use especially in 5/6 mark calculations where multiple formulas are needed
Try to follow these steps, and practice with past papers as much as you can

@@captainphysicss thank you🙏
Hi, for the diagram, how do you know which angle to measure as there is another one in the same corner you could measure? Also why do you draw it flipped (is there a reason for this)?
The mark scheme allows either angle, as long as you show on the diagram. Sometimes it may specify a particular one
What do you mean "flipped"?
@@captainphysicss isn't the angle meant to be in bearings? like 060 degrees from north for example?
@@chosen9010 not for AQA, not sure about others
Thank you SIr.
one little question; don't we need to draw the vectors head to tail in the first question?
Yes that is the more correct way -- you would at A-level. AQA mark schemes use this way though
@@captainphysicssWould I still get the mark for doing it tip to tail?? That's how I learnt it!
Sorry late replying! @@tabitharrr2642 yes that's fine should get you the same answer
@@captainphysicss thanks, luckily it didn't come up on my paper! (Triple higher)
@@tabitharrr2642 that's good, hope it went ok!
When i did q1 i got 158N and 18 degrees. Would that be in the correct range?
Yep, well done
but speed = distance/time , why have you said speed=distance x time for the last question?
I haven't,.it's just the symbols - s is used for distance

@@marriam650 whoops.. my bad! Well spotted. I meant speed = distance / time
Is this for edexcel?
Mainly AQA
AQA
for the first question could you not just use pythag and trig?
Yes, but AQA want a diagram - as it says vector diagram in the Q
@@captainphysicss ok thanks, appreciate it
keep up the hard work💪

I'm nosy can I know what caused this sound
I was hoping no one would notice...
An advert on P&MT started playing 🙈
For the last question, shouldn’t we round it to 16
No as it says number of "complete" orbits - so we would round down
no because it says how many complete orbits, it does not make 16 complete orbits it only makes 15 complete orbits
4:40 could you use pythagoras
yes
To check your answer yes, but the question says a vector diagram which is what it wants for full marks
