two objects are connected by 1.0 m long massless bar. One object has twice the mass of the other. They begin spinning with a constant angular speed of 15rad/s around point P that's equidistant between the two objects. Suddenly, the bar streatches and the larger mass is further from P. The angular speed decreases to 9.6 rad/s. By how much did the bar stretch?
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.
