I feel it would help to distinguish between vectors and scalars, since you are using the same symbol for both. Here: given that v and r are always perpendicular: v. r = 0 (dot product) d/dt both sides: a. r + v. v = 0. a. r = -v 2. a. r = -ar (since they point in opposite directions) a = v 2 / r.

Web10 years ago. No! ω is the angular velocity. And yes, usually, this is a vector quantity - but only if you use the "real" definition ( *ω* = r x v / r ² ). In your case, the argument has to be: dθ/dt = ω; Theta is obviously a scalar - cause θ and φ almost always are angles. Thus, ω is a scalar quantity in your case. WebNov 22, 2024 · Then, you connect the two points to the center, and label each line r, and the angle between them θ.
