Linear Velocity is a physical quantity that shows the change in position per change in time that moves in a straight line. However, in circular motion it is always tangent to the circular or curved path. Not to be confused with the angular velocity that shows ...

Velocity, quantity that designates how fast and in what direction a point is moving. A point always moves in a direction that is tangent to its path; for a circular path, for example, its direction at any instant is perpendicular to a line from the point
Angular velocity is when an object is rotating around a center point in a circular motion. Like other types, it is measured by how far the object has traveled over time. Since the object is moving in a circular path, the angular distance can be measured in radians, degrees, or ...
