Velocity is a vector that is fully described by a numerical value (such as 20 m/s) and a direction. Objects that move along a circular path have a velocity vector that is directed tangent to the path.

There are four similar versions of this question. Here is one of those versions:

Version 1:

An object is moving clockwise along the circular path as shown. Identify the direction of the velocity vector at Location A.

Your task involves determining the direction of the velocity vector. You can tap on the Change button to toggle through all eight options. You're looking for the one option that is in the direction of motion and tangent to the circle. In describing the velocity vector as being tangent, we are saying that it is in a direction that, if extended, would only touch the circle at only one location. You will find two such tangential vectors. Pick the one that is in the direction of motion - clockwise. The small arced arrow displayed inside of the circle shows which way clockwise is.
