    Never came across a video that explains a concept so thoroughly. You explained the thought process behind answering, the reasoning behind each step, and worked through the exercises with us which is exactly what I was looking for and needed to fully understand. Thank you kind sir. Your work is really appreciated.

    @UthixunamHewu__ Год назад +1

    This made sooo much sense, thank you so much😩
    Question:
    I see when you write the formula for example at the inclined plane, 3rd question to find the gravity, this question is basically for all the questions but I'm going to use that one as reference, I noticed how you write it as: Wg//=Fg//.change in x.cos of angle
    I write as: W (Fg// as a subscript since it's the work by that component) =F (Fg// again as subscript). change in x.cos angle
    Does it matter how you reference it? I'm asking mainly because my physics teacher at school does not mark the rest of the sum if one's formula is incorrect so I'm making sure of finer detail...
