A flywheel with a diameter of 1.00 m and initially rotating at an angular speed of 500 revolutions per minute (rpm) changes its angular speed at 1000 rpm after 20.0 s. Assuming a constant angular acceleration, find its value in (rad/s2), the angle through which the flywheel turns in moving from 500 rpm to 1000 rpm. (in degrees) the acceleration of any point on the rim (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.
