Which symbol denotes angular velocity?

Which symbol denotes angular velocity?

• A. Alpha
• B. Omega
• C. V
• D. P

Answer: (B)

Angular velocity tells you how fast something is spinning and in which direction. The symbol used for this in rotational motion is Omega. Its magnitude is measured in radians per second, and as a vector it points along the axis of rotation (direction given by the right-hand rule). The other symbols correspond to different ideas: Alpha is angular acceleration (how quickly the rotation rate changes), V is linear velocity, and P is momentum (or pressure in other contexts). So Omega is the only symbol that directly denotes how fast something rotates, making it the correct choice.
