ar is traveling along a road, and its engine is turning over with an angular velocity of +190 rad/s. The driver steps on the accelerator, din a time of 10.0 s the angular velocity increases to +300 rad/s. (a) What would have been the angular displacement of the engine if angular velocity had remained constant at the initial value of +190 rad/s during the entire 10.0-s interval? (b) What would have en the angular displacement if the angular velocity had been equal to its final value of +300 rad/s during the entire 10.0-s interval? Determine the actual value of the angular displacement during the 10.0-s interval. ) 0= 0 0= 0= < i IP Mi

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.
