A clinical blood centrifuge operates at ω= 1200 rpm. a.) What is the angular velocity measured in radians per second? b.) With a radius of 8.5 cm, g=10 m/s^2 and ω= 1200 rpm what relative centrifugal force should we measure? c.) The machine decelerates to a rate of α= -40 rad/s^2 from an initial angular speed ω=1200 rpm. How long will it take the centrifuge to stop? How many rotations did it turn? d.) If it takes thirty seconds to stop from an initial angular speed ω=1200 rpm, what angular acceleration did it experience and through how many rotations did it turn?
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.
