Bodies following a circular path with constant angular velocity travel in a direction tangent to the circle at any given point. This direction is perpendicular to the radius of the circle at that point.
To understand this concept, let's consider a body moving in a circular path with a constant angular velocity. Angular velocity is the rate at which the body sweeps out an angle as it moves around the circle. The magnitude of the angular velocity remains constant, but the direction changes as the body moves.
At any point on the circular path, the body has a velocity vector that is tangential to the circle at that point. This means that the body is moving perpendicular to the radius of the circle at that particular point.
In other words, if you draw a line from the center of the circle to the point where the body is located, the body's velocity vector would be perpendicular to that line, pointing in the direction of motion along the circular path.
It's important to note that this direction is constantly changing as the body moves along the circular path, but the magnitude of the velocity remains constant due to the constant angular velocity.
