i love how in the vid hes rly formal and when hes in the comments hes so chill but epic teacher anyhow. Taught me in 20mins what my phys teacher failed to do for 4 lessons
i'm using this playlist to revise for my Alevel mocks ( in 2 weeks) and its very quick and useful and you explain everything so well in such a short time so thankyou sooo much for that!!
These videos are timeless! My exam is tomorrow so I’m doing some last minute revision and luckily stumbled across your channel. I found your videos so helpful, finally understood these types of questions (and even learnt a useful trick ;D). Thanks for the upload!
Love From India ❤ In my whole classes when there is to be deal with vector or resolving vector I got very confused but by today onwards by watching your Video i got more confident ! Now i expand my learning Thanks Man !✌
I have a physics quiz soon and your videos really helped a bunch! I have never understood forces as well as after I have watched your videos 😂 Thank you!
Someone give this man a medal! The effort is amazing man and it really does help. Great trick btw - I saw it earlier at school but did not understand how it was brought into play. Thx for that as wekk
Hi sir. The one thing I don't understand in here, even after watching the easy vectors trick, is what you mean by going "through" or "not through" the angle. Where do you start from when turning "through" the angle? Thanks.
You know when you have a vertical and horizontal component to a resultant? So if your given angle is towards the vertical side you would have to get pass the angle to get to the vertical which means you have to use cosine, and you would have to move away from it to get to the horizontal component which means you have to use sine
Thanks for making these. Not only are they useful but they're interesting. Please could you cover more exam questions? I am doing AQA but I guess looking at any papers would be a big help. Mark schemes aren't very useful espicially for multiple choice.
it is very helping video , but I have question sir what happen to the portion of the force ( 15 cos 35) opposite to 20 N ( at 7 min of video ) ? it should be in as well isn't ?
Can anyone tell me what turning towards/away from the angle means? Like... is it the same for any angle anywhere in any scenario, and yeah I just don’t get it. Please help! :)
Prodigy if you are talking about the tightrope gymnast example, I got confused at first as well. The weight is 90g as g in this case is referring to acceleration due to gravity! The gymnast has a mass of 90kg, and to find weight you do mass times by g, and instead of writing out the answer he has just said 90 x g, where g = 9.81. So g isn’t a unit, it refers to a value, and he should have put the unit for weight, which is N!
Emad Islam its abit different here, normally if its TO the horziontal then vertical is sin and horizontal is cos. IF ITS to the vertical then vetical is cos. And horizontal is sin. Umm the WHY to this is actually deriving it using trigonemtry
No-one said it was easier - this is quicker, because you don't have to spend valuable seconds figuring out what side of the triangle you have. Give it a try!
Thank you for getting to the point and not causing any confusion. Your videos are some of the most clear videos on this topic find in UA-cam.
hear hear
'Life's too short to draw millions and millions of triangles' - That, I understand :D
Put that on a t-shirt
i wish there were more examples considering different scenarios because the way you solve the problem is extremely helpful. thanks a million times .
That's where past papers come in!

Watching these videos a day before my As level physics
How was it

watching a basic forces video a day before phy exam? hahahahha coool

At 6:00 it should be 15 cos 35 for the horizontal component and 15 sin 35 for the vertical component
yess exactly
@@vidausman4381 I take back what I said actually, the angle is between the vertical here and not the horizontal
Someone give this man a medal!
The effort is amazing man and it really does help. Great trick btw - I saw it earlier at school but did not understand how it was brought into play. Thx for that as wekk
for the question @ 7:37 could we also just form a parallelogram and use the cosine rule?
I love you ! Thank you so much i always thought i could never understand physics
Holy fuuu I don't think I can thank you enough sir honestly banging out these questions and starting to get them right
Thank you for making these
A genuinely beautiful video. Thank you.
My u1 exam is after 4 days (10th jan)
I have the worst worst worst preparation ever. But you're a lifesaver. Thank you so much
This feels like some form of magic. Suddenly this kind of question isn't as scary anymore!
This is awesome! I hope it still gives the marks though. So many of your videos make life SO much easier!

If i do with triangle method, the horizontal component is 15 cos35 so the vertical becomes 15 sin35
I am confused now
Thank you for making these videos, they have helped me so much!!
Watching this before my exams, great video well explained
At 3:30 you mark 35° to the vertical
When resolving the vector shouldn't (90-35) be used so sin(65) cos(65)
Thanks for making these. Not only are they useful but they're interesting. Please could you cover more exam questions? I am doing AQA but I guess looking at any papers would be a big help. Mark schemes aren't very useful espicially for multiple choice.
Thank you a million times seriously i finally could solve these kind of problems easily
This was really helpful man, thank you!
Woowww man! This really makes sense🙂 u ve saved my life😃
it is very helping video , but I have question sir what happen to the portion of the force ( 15 cos 35) opposite to 20 N ( at 7 min of video ) ? it should be in as well isn't ?
are you a boxer? or have you done boxing before?
Why you ask?
Hello , love the video very helpful but do know of any worksheet or practice questions that that i could use to practice ??
How is 882 / 1.23 equal to 719N, isn't it 717.1 N? @ 16:42. Also the content of this video is very useful for physics revision.
@15:18 isn't the weight 0.882N because the mass is in grams not kilograms?
Thats what i was thinking
Not sure if you're joking or not but the mass was in kg. 90g is in reference to 90 * g where g is 9.8ms^-2
13:43: So the mass of this person is 90kg .. quite a heavy guy
Me who is exactly 90kg rn: 🥲🥲🥲
I can't deal with weight in kg - only old school stones 😂
@@ScienceShorts lmao
It took me 5 episodes in this playlist to realise what he meant by "Turn away from sin" XD
Can anyone tell me what turning towards/away from the angle means? Like... is it the same for any angle anywhere in any scenario, and yeah I just don’t get it. Please help! :)
Watch his easy vector video thats where he explains it
This video is so good thank you!
You know the question at 4:45, could you use cosine rule to find the Resultant Force
Never been a fan.
The gymnast weights near a metric ton
For the last one in mcq, what if they give the imside angle and the weight and the options for force acting on the cables
Extremely helpful!
I think you interchanged cosine and sine on the second example.
Thank you so much bro, keep up the great work
Why dont we take the axis into consideration like for the horizontal axis??
why does the T2 disappear from the equation? arent u suppose to times it?
in the first equaion, why did you use the pythagorases theorum?
Thanks a lot. These videos are really useful!!!
can you cancel cos30/cos40 to tan40?
Nope
Hi Sir. I would like to ask: since mass' SI base unit is kg, shouldn't the mass first be converted from g into kg?
Thanks, in advance.
Prodigy if you are talking about the tightrope gymnast example, I got confused at first as well. The weight is 90g as g in this case is referring to acceleration due to gravity! The gymnast has a mass of 90kg, and to find weight you do mass times by g, and instead of writing out the answer he has just said 90 x g, where g = 9.81. So g isn’t a unit, it refers to a value, and he should have put the unit for weight, which is N!
@@harrietjones1409 Thanks a lot! That rly cleared my confusion!
Prodigy no problem! Good luck with your A levels!
aren't we supposed to convert 90g to kg since that is the SI unit before converting it to Newtons?
🙄
🙄
🙄
you are great, much love from me
Could you please explain to me why we don't substitute the horizontal equation into the vertical equation on T2sin(theta2 as well at 12:20
Thank you
Because it's just easier to do so. You have MG on the right side of eq.1, so it's simpler to just sub in eq.2 into eq.1 and then solve it
Even I thought 35 degree was written for horizontal but 35 degree is written to the vertical and so it is 55 degree to the horizontal
Could you use cosine rule ?
thank you so much man one thing how come you used mass in grams here
That's not grams dude, it's the mass x g
ahhh apologies good sir
is this in the aqa a level physics spec?
Nabin Gurung yep
so helpful thank you!!
great and useful vid tks
You did 90 multiplied by g, but it was 90 grams, so shouldnt the force of weight be 8.82N?
Eric Jeffrey 90kg times g (gravitational acceleration)
@@SwifTPickAxeZ oh I see., I mistook 90g for 90 grams, cheers
Yh i made the same mistake
Really useful thanks
I'm confused...I always thought the x axis was for COS and Y axis for SIN
Nope - it depends on which angle you're given.
really helpful thank you
Thank you so much
Sharpie needs to sponsor u, thnks bro gr8 help
Thanks a million
Surely the horizontal one would be cos and the vertical one would be sin?? You have done it the wrong way round I think
+Emad Islam You can think that all you want mate.
Emad Islam its abit different here, normally if its TO the horziontal then vertical is sin and horizontal is cos. IF ITS to the vertical then vetical is cos. And horizontal is sin. Umm the WHY to this is actually deriving it using trigonemtry
Emad, here it is 55 degrees to the horizontal and 35 degree to vertical
Btw I’m pretty sure my a-level physics teacher used these questions in our class in the beginning of this term 😭😭😭
This was extremely helpful thanks a lot
all my problems in life would be solved if you were my teacher
If I took theta to equal 55 from 90-35 instead of using the 35 would it still work out?
yes it does . you can use 55 to find 8.6=(15cos55) but eventually you will need the vertical component to find resultant
its 90 grams, shouldn't you have converted it to kg?
90 x g
You keep talking about how good your trick is but honestly it’s not that hard to use sohcahtoa.
No-one said it was easier - this is quicker, because you don't have to spend valuable seconds figuring out what side of the triangle you have. Give it a try!
Thankyou!
thanks
can you not just use the cosine rule for the question at 3:10 ?
Awesome
I want to marry this man. Thank you so much!!
I love you
i love u
you a mistake bro i think u change 90grams to kilo grams. just helping out brother❤.
Good grief - how many times do I have to reply to this comment.
That's 90 x g 🙄
Lol
my teacher cant draw cars at all
Chances are, like me - he/she can, but it's more entertaining when we pretend we can't. 😉

50kg is heavy??? You must be confused. That’s like a normal weight for a teenager.
Got any more snarky comments for my videos? That's 3 in a couple of hours. Also, who upvotes their own comments? 😐
@@ScienceShorts absolute boss
90kg instead.
+Giovani Pitra Nope. The force is 90kg x g, or 90g for short.
I love you
