      Thank you very much for the response, I will keep on trying to work on more videos if you have any papers you faced difficulties accessing please do mention them and if you have any challenges on questions just shout👍👍, Stay Humble, Stay Curious, Physics is far greater and fun than people think

    Sir you put alot of effort into these videos thanks Alot! still am amazed how did the examiner give a university level question in this paper mcq 12 was 🤯

    for q23, why not B, i thought at B highest kinetic energy
    by the way thank you for the video until now u are the best at explaining physics

    • @Alevel_Physics

      Okay at the maximum displacement the velocity has to be zero so that you turn back and actually reach maximum, so velocity can't be at maximum because we can't reach a max displacement if the velocity is not zero. I hope it makes sense do ask if you have any concerns

    sir, at 40:02 i have also heard that particles at equilibrium do not move, if im wrong can u plz explain when does that concept apply?

    • @Alevel_Physics
      @Alevel_Physics  5 месяцев назад +2

      Particles at equilibrium do move, but its just that at that point in time the displacement from equilibrium will be zero, but moments later the particles are still moving up and down, so there are no particles that do not move, All particles move up and down at any given time

    sir, why does steel and brass both have the same force of 40? shouldnt it be 20 each? 34:21

    • @Alevel_Physics
      @Alevel_Physics  5 месяцев назад +2

      Ok 👌, good question, since the steel and brass are in series (one after the other) they both experience the same force of 40 N, so the steel is carrying the load and the brass is also carrying the load and the weight of the steel wire, but we might assume that the weight of the steel is negligible in a way

    5:52 why did you put 12 in place of uncertainty to calculate percentage uncertainty?

    • @Alevel_Physics
      @Alevel_Physics  6 месяцев назад

      Thank you very much that is an excellent question.
      *****
      So the question said error, now if you look at an error, you were supposed to get something but you got something else so error = actual value-measured value
      The percentage error will be that error divided by the actual value *100.
      ****
      So I used 12 as my error and 600 as my actual because look if we lose 6 on this side and 6 on that side the new reading will be 588 so error = 600-588 = 12
      ***
      It is worth noting that people, including myself often use error and uncertainty interchangeably but they are actually pretty different, an uncertainty is a range we give ourselves and we expect the actual answer to lie in that range, and an error well is just the difference in what we got and what we actually had

      @Life_and_academic_Motivation thank you so very much for replying. i was spending the past hour or so very confused with this question, and i understand it now. you also clarified a doubt i had about the difference between errors and uncertainties, so thank you.
