Angular velocity is a measure of the rate at which an object is rotating around a specific axis. It is typically measured in radians per second (rad/s) or degrees per second (deg/s).
Angular velocity and angular acceleration are closely related, as angular acceleration is the measure of how quickly an object's angular velocity is changing. In other words, angular acceleration is the rate of change of angular velocity.
The formula for calculating angular velocity when given angular acceleration is ω = ω0 + αt, where ω is the final angular velocity, ω0 is the initial angular velocity, α is the angular acceleration, and t is the time interval.
The direction of angular acceleration determines the sign of angular velocity. If the angular acceleration and angular velocity have the same direction, the angular velocity will increase. If they have opposite directions, the angular velocity will decrease.
Yes, both angular velocity and angular acceleration can be negative. A negative angular velocity indicates that the object is rotating in the opposite direction of a positive angular velocity, and a negative angular acceleration indicates that the object is slowing down its rotation.
