A rotating disk with an angular velocity of 3 rev/s is brought to rest in 12 seconds by a constant torque. How many revolutions does the disk turn before it comes to rest? 72 rev 18 rev 36 rev 54 rev
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.
