Angular acceleration is a measure of how quickly an object's angular velocity is changing over time. It is measured in radians per second per second, which represents the change in angular velocity over a one-second time interval.
Angular acceleration is calculated by dividing the change in angular velocity by the change in time. This can be represented by the formula alpha = (omega2 - omega1) / (t2 - t1), where alpha is angular acceleration, omega is angular velocity, and t is time.
The unit of measurement for angular acceleration is radians per second per second, which can be abbreviated as rad/s² or rad/s^2.
Angular acceleration measures the change in angular velocity over time, while linear acceleration measures the change in linear velocity over time. Angular acceleration is typically used to describe rotational motion, while linear acceleration is used to describe straight-line motion.
The angular acceleration of an object can be affected by its mass, the force applied to it, and the distance from the axis of rotation. Other factors that can affect angular acceleration include friction, air resistance, and the shape and size of the object.
