A wheel is rotating counter clockwise initially at an angular speed of 2.50 rad/s. Itdeceleratesover a 4.0-s interval at a rate of 0.140 rad/s2. a)What is its angular speed after this 7.0-s interval? b)What is the angular displacement? c) How long would it take for it to stop?
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.
