A wheel is rotating about an axis that is in the Z-direction. The angular velocity ωzωz is -6.00 rad/srad/s at tt = 0, increases linearly with time, and is +4.00 rad/srad/s at t = 14.0 ss. We have taken counterclockwise rotation to be positive. Is the angular acceleration during this time interval positive or negative? positive negative

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.
