Two children are on the edge of a merry-go-round. One child weighs 25kg, the other 30kg. If the child weighing 30kgs moves to the center of the 75kg merry-go-round, what is the new angular velocity of the system? The merry-go-round rotates at 15rmp with a radius of 1m.
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.
