A record player works at a clockwise angular speed of 3.53 rad/s, and takes 1.06 s to steadily accelerate up to that working speed when it is first switched on. Use radians as the standard unit for angles. What is the final angular speed of the record, in given units? 202 %/s 0.562 rev/s 33.7 rpm What is the magnitude of the angular acceleration of the record, in given units? 3.33 rad/s2 What angle does the record rotate through during the acceleration period, in given units? rad rev O
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.
