There exists a 0.35 m radius turntable that has a constant angular acceleration of 0.145 rad/s2 from rest. How many times does this turntable rotate in 12 seconds after the acceleration begins? After the acceleration begins, how long does it take for the magnitude of the acceleration of a point on the rim of the turntable to reach 0.12 m/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.
