As far as I rmbr, in highskl (and physics 1) u only learn to figure out the force needed for acceleration and what not and kinda ignore the stuff aftermath posted in the video, tho maybe I was just sleeping in those lessons and since it wasn't on the exams it didn't mtr... Tho ofc u can kinda get to the realization alone if u know enuff..כשחושבים על זה יש מצב מועט שלמדתי את זה גם בפיזיקה. @Koller נא לאמת.
