A rod 2m long rotates in a horizontal plane about a vertical axis through its center. At each of the rod is fastened a cord 1.200m long. Each cord supports a bob of weight W. Find the speed of rotation n (in rpm) to incline each cord at 320 with the vertical
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.
