Great! Thank you. I have one question. You draw acceleration in the second picture on the top of velocity, but in the first picture (circle) you draw acceleration on the bottom of velocity vector? why? It doesn't matter where you draw it?
-
me ha tomado dos años entender esto gracias a udsted de una forma muy clara
-
I thank you , really, because in my class I didn't get it clearly .
thanx thanx thanx

@Wid552 Velocity is a vector. It has a direction, and a magnitude. If it was a scalar it would have neither. [Speed is a scalar, velocity is a vector]
-
(Continuing from my 1st comment) Is the velocity vector just directional?
-
For the second circle, could you explain how the radius of the second circle represents the velocity? Or could it be represented in the same way by placing the velocity vectors on the circumference? Or is it just purely representative, regardless of positon?
-
QED
-
The radius of the circle drawn on the right isn't the circle with radius = r. It's a visual representation of how a relates to v ( v and a replotted). Rendering your comment WRONG
-
hey the radius of circle is not the magnitude of velocity!! rendering this proof WRONG

great visual presentation, helps understand the idea of derivatives of position and speed.
