    That is the most perfect theta I've ever seen

    no other video explains this topic as well as you do, in my opinion. Thank you so much for your help. Truly grateful.

    Just wanted to say the way you explain any subject in maths, regardless the difficulty, it is alway in a thorough, clear manner! Thank you so much for sharing with us!

      Yh me too, would this A level maths videos on inclined planes give us all the information we need for our physics exam? ???

    • @gyrus2251
      @gyrus2251 2 ปีที่แล้ว

      @@saile_1994 for inclined planes? yh pretty much. the only other thing is general knowledge of physics for questions with scenarios that combine other topics like particles or further mechanics.

    Hi, i was asking if its weird to be learning year 13 A-level content in year 12, because people from different schools are only learning as content this year.

    • @TLMaths
      @TLMaths  2 ปีที่แล้ว

      Due to the linear nature of the course, teachers deliver the course in all sorts of different ways and aren't bound by "year 12" and "year 13" content. Where I teach, we teach all of the AS content in year 12, alongside a few choice full A-Level Maths topics when we believe it's appropriate.

    what I hate and don't get about the whole problem is not the calculations but the fact that physicists just made up the rule that the breakdown forces will break down exactly and proportionately to sides like in a right-angled triangle. It's like describing reality using just simple shapes or cute assumptions. Is there actually any measurable proof that the forces would break down like side lengths in triangle? Second annoying thing is that despite drawing two vectors into which the gravity breaks down, we only consider the one perpendicular to the surface as the normal reaction force? Let's imagine the slope being really super steap, would we still ignore the other vector? (or is this left to be introduced as friction later on?)

    • @TLMaths
      @TLMaths  3 ปีที่แล้ว

      Yes it is measurable. Tugboats for example, pulling a cruise ship north and east - you would be able to see the direction the cruise ship is travelling. If the tugboats are pulling with the same force, then the cruise ship will travel north-east. So pulling north and east would be equivalent to a tugboat pulling north-east. Therefore one force can be broken up into two components.

    • @gyrus2251
      @gyrus2251 2 ปีที่แล้ว

      Horizontal and vertical components are independent. So like imagine a table, one ball is magically suspended above the ground at the height of the table and the other ball is on the other side of the table. The second ball will be rolled along the table and the moment the second ball leaves the surface of the table the first ball drops. the second ball will obviously not suddenly plummet vertically down but will travel some distance forward and descend at the same time. The first ball and the second ball both reach the floor at the same time. This is because the components are independent and when no other forces act on it (excluding gravity as that would make the entire scenario fail) they hold the same value. Its more like reality is a bunch of lines, many many lines and making triangles is a very easy and simplistic way to predict stuff. If say there was no gravity acting, they would travel the same distance given the same force.

    Why do we have to resolve weight perp. and parallel to the slope and not like forces in a cartesian plane?

    • @TLMaths
      @TLMaths  4 ปีที่แล้ว +4

      Because it's so much easier to do it that way, as parallel to the slope is the direction the particle is travelling in
