What is angular velocity?
Q: What is angular velocity?
A: Angular velocity specifies the angular speed at which an object is rotating along with the direction in which it is rotating. It is a vector quantity.
Q: What is the SI unit of angular velocity?
A: The SI unit of angular velocity is radians per second.
Q: Can angular velocity be measured in other units?
A: Yes, angular velocity may be measured in other units as well such as degrees per second, degrees per hour, etc.
Q: What is the term used when angular velocity is measured in cycles or rotations per unit time?
A: When angular velocity is measured in cycles or rotations per unit time (e.g. revolutions per minute), it is often called the rotational velocity and its magnitude the rotational speed.
Q: What symbol is usually used to represent angular velocity?
A: Angular velocity is usually represented by the symbol omega (Ω or ω).
Q: In what direction is the angular velocity vector perpendicular to?
A: The direction of the angular velocity vector is perpendicular to the plane of rotation, in a direction which is usually specified by the right-hand rule.
Q: Is angular velocity a scalar or a vector quantity?
A: Angular velocity is a vector quantity.
