### Understanding Angular Velocity **Question:** Which of the following describe angular velocity? **MARK ALL THAT APPLY** - **A) the speed of rotation** - **B) the angle traveled through (either radians or degrees) divided by the time it takes** - **C) how fast the object is speeding up in its rotation** - **D) the angle an object turns through** ### Explanation: - **Angular Velocity Defined:** Angular velocity refers to how fast an object rotates or revolves relative to another point, typically the center of a circle in which the object is moving. It is often described in terms of the rate of change of angular displacement and is usually measured in degrees per second (°/s) or radians per second (rad/s). - **Key Aspects:** - Angular velocity involves both **direction** and **magnitude** (speed of rotation). - It is a measure of how quickly the object moves through an angle (option B captures this essence well). **Note:** In the context of angular motion, options A and B are typically relevant to angular velocity. Option C refers to angular acceleration, not velocity, and option D describes angular displacement rather than angular velocity.
