s Some dragonflies are observed to splashinto the water to bathe, and then spin rapidly to shed the water.Slow-motion video shot at 240 frames per second shows that dragonflies complete one spin revolution every 14 frames. What is thespin rate of the dragonfly in revolutions per minute (rpm)?
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.
