Suppose you have two rotating disks. Disk 1 has a constant angular velocity of 10rad/s, and Disk 2 starts at rest but has an angular acceleration of 2.0rad/s^2. How many radians will be traveled by each disk by the time they cover the same angular displacement? Would your answer change if one of the disks doubles its radius but changes nothing else?
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.
