Guess my physics professors back at university were wrong then ¯\_(ツ)_/¯
Yes he was. You should ask for your money back. I don't know how you'd complete even intro physics getting this wrong, as the formulas all depend on it.
This is like high school physics - change in direction is ~~a change in~~ acceleration.
Even better, you can experience this directly - turn the wheel abruptly at a moderate speed - what you feel is called acceleration.
Did your physics professor say "velocity == speed"? Because if so, yes he was
Maybe it was a one-dimensional physics professor
If they said that, yes, they were.
Doubt it, I'm going to go out on a limb and say either you didn't take university physics or you weren't paying attention, because like the other commenters said this isn't even university-level physics knowledge, it's highschool.
What have you done to those poor arrows? 😭😭
