A ceiling fan that was rotating with an angular velocity of 12.6 rad>s begins to slow downwhen it is turned off. How much time does it take for the fan to come to rest if it has a constant angular acceleration of - 0.168 rad>s2?
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.
