Now I can use the video version of the same thing and Tracker Video analysis to get the following plot of horizontal position vs ... acceleration is defined as: The slope of the velocity-time ...

If the angular velocity of a ... some time “t” is the FUNCTION value of ω(t). On the other hand, the angular acceleration α(t) is the TIME DERIVATIVE of ω(t): α(t) = dω(t)/dt. Visually, if you make a ...
