Angular acceleration is the rate of change of angular velocity over time. It is a measure of how quickly an object's angular velocity (rotational speed) is changing.
Angular acceleration can be calculated using the formula α = (ω2 - ω1) / t, where α is angular acceleration, ω2 is the final angular velocity, ω1 is the initial angular velocity, and t is the time interval.
Angular acceleration is typically measured in radians per second squared (rad/s2). However, it can also be expressed in degrees per second squared (deg/s2).
Angular acceleration and linear acceleration are related through the distance from the axis of rotation. The further away an object is from the axis of rotation, the greater its linear acceleration will be for a given angular acceleration.
To find the angle in 2 seconds, you will need to know the initial angular velocity and the angular acceleration. Use the formula θ = ω0t + 1/2αt2, where θ is the angle, ω0 is the initial angular velocity, α is the angular acceleration, and t is the time interval (in this case, 2 seconds).
