You're welcome

ExamSolutions I have a doubt how can we tell in which direction the force will move ?!! Please tell

@velvetwisteria6237 4 года назад

@@sheetalwalia9637 For which example are you asking the question ? If it's for the 6N and 8N example, then the direction goes from the starting point where the particle is to the head of the last vector that you drew .

you really should write textbooks, you would get a lot of sales. many people including myself struggle to make sense of what the textbooks we are using say, yet get the concept very quickly once we watch your videos. if you did start writing textbooks I would buy them.

@ExamSolutions_Maths 8 лет назад

Thank you but I think I will keep going with the videos and trying to improve the website

@perpetualtom6649 7 лет назад

textbooks are always going to be like that for maths though. unless you want to include a full peter narrative with each page

@davidgoodman8469 7 лет назад

at the time I was starting I was using CGP text books, which I don't care what people say are god awful at explaining anything. i have since found text books that explain things well, so I just had bad resources when I started. Although exam solutions videos are normally more efficient then the text books.

Omg, I had so much struggle figuring out what my Phys. lecturer was showing us. But once I watched ur vid, I understood instantly. I'm pretty sure I aced my test btw. So thanks

@dolphinpower1107 3 года назад

But how do you calculate the direction of a resultant force.

@ExamSolutions_Maths 3 года назад

Find the angle to the horizontal of the resultant force (generally use SOHCAHTOA).

@dinopuff7354 2 года назад

Thank you So MUCH my gosh, going through blinkin A-level's and i still can't get my head around this concept, and how people are solving it and by 3 minuites i've already got perfect clarity on how it works, Thank you!

@anshuiyakarki5922 3 года назад

why did you add 8 while resolving horizontal component and why didn't you add 8 while resolving vertical component?

@madblox252 9 месяцев назад

to find RN can I also use pythagoras theorem? I got 10N.

@mustafakadhum5370 6 лет назад

Thanks Alot I struggled to understand the relation between the vector triangle law and the component forces but when u placed them side by side realised that the triangle law of vectors uses the cosine rule since its not a right angle triangle otherwise the component forces method creates a right angle triangle so allows trigonometry thanks alot

@ExamSolutions_Maths 6 лет назад

No problem. Pleased to hear it helped.

sir. when will i use cos or sin? im confused. and what angle will i use.?

@Rebekah_xo 3 года назад

Thank you for this sir, do helpful! Do we need to know how to do it both ways or can we just stick with the first method?

@mush2224 12 лет назад

thank you I've been looking for ages for a video like this all the one I found I either couldn't understand what they were saying or they were talking about area. Thanks

@yasminaosman3296 10 лет назад

Ok.If forces are vectors, why not just add them up to get the third force in the triangle? I mean, you've applied pythagoras and cosine rule to get the third force instead of just adding up the other 2 vector forces.Why?

@samass44 11 лет назад

that helps me a lot!! Thank you

@neerajmodi6794 Год назад

You cleared my doubt, Thanks teacher 👍

@ExamSolutions_Maths 10 лет назад

I am showing various methods. If I did do a vector method then i will have to resolve to get the components then to get the magnitude use Pythag anyway, so what is the difference? The methods are still the same.

@sheetalwalia9637 4 года назад

If the forces are in the same side we add them but if they are opposing each other we subtract to get the resultant or net force

Hi please in my question the body is given a mass of 50kg, how do i determine the acceleration of the body and the angle of inclination of the resultant to each of the vectors.

@TheNathanael315 8 лет назад

Why cant you leave the 2 forces in the 3rd example where they are and get the answer, I tried to do the example as I did in the M1 jan 2006 paper (question 4)

@ExamSolutions_Maths 8 лет назад

You should be adding vectors to get the resultant. So you must put one vector on the end of the other as I did. If you did it the way you are suggesting then the magnitude and direction would be wrong.

@TheNathanael315 8 лет назад

yes, I'd like to know how to find the direction as well!

@tgdhsuk3589 7 лет назад

i dont get wht u mean, think of a question, because they cant give two forces and no angle, its either all forces or hints in the question... I think otherwise I'm screwed
