**Problem Statement:**A turntable rotates with a constant angular acceleration of 1.85 rad/s² in the clockwise direction. After a duration of 4.00 seconds, it has rotated through a clockwise angle of 30.0 radians. **Question:**What was the angular velocity of the wheel at the beginning of the 4.00 s interval?---For a detailed answer explaining angular velocity and its applications, this question would be part of a physics or mechanics lesson focusing on rotational motion. The angular velocity is typically measured in radians per second (rad/s) and can be determined using various kinematic equations or graphical data from an experiment involving rotational dynamics.

Angular speed, acceleration and displacement

Angular acceleration is defined as the rate of change in angular velocity with respect to time. It has both magnitude and direction. So, it is a vector quantity.

Angular Position

Before diving into angular position, one should understand the basics of position and its importance along with usage in day-to-day life. When one talks of position, it’s always relative with respect to some other object. For example, position of earth with respect to sun, position of school with respect to house, etc. Angular position is the rotational analogue of linear position.
