A fan is rotating at a constant speed of 60 rpm. The fan has a diameter of 0.50 m and coasts to a stop in 30 seconds after being turned off. How fast is the fan rotating before it is turned off With what acceleration does the fan slow down
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.
