    I wonder if it’s like the grading system we use in school? <60% is F for fail, 60% to <70% is D which depending on the class can be barely passing or barely failing. >=70% would be A, B, and C grades which are all usually passing, and A in particular means doing extremely well or perfect (>=90%). I just noticed that that rating scale kind of lines up with the typical American grading scale, maybe that’s just a coincidence






  • Acceleration and velocity are both vectors dude, they have magnitude and direction. Acceleration is a change in velocity over time, so if you’re moving and you change directions, that constitutes a change in velocity, i.e. an acceleration.

    Hell, Newton’s second law: F=ma. Your car isn’t going to change mass appreciably mid-corner, so we can say that the force you feel is proportional to your acceleration. Did you feel yourself turning? Felt your ass slide and body lean? You feel you experience a force, an acceleration.

    This concept is foundational to elementary mechanics, you cannot pass physics 1, calculus 1, or I think even college algebra without knowing these concepts.
