Does speed have a vector

WebA vector stores only two parameters of information - length and direction. It doesn't tell you anything about it's origin/location. It can vary with time if it's given as a function of time, for example if the vector symbolises speed of an accelerating object, then it does vary on … WebNov 5, 2024 · The velocity vector, \(\vec v\), is always tangent to the circle. The acceleration vector, \(\vec a\), is always perpendicular to the velocity vector, because the magnitude of the velocity vector does not change. The acceleration vector, \(\vec a\), always points towards the center of the circle. The acceleration vector has magnitude \(a=v^2/R\).
