You stretch your arm and rotate around the center of yourself in horizontal plane. Suppose you make 2 full revolutions every 1 second, and the distance from the center of your body to the tip of your finger is 1.2 m. Find the angular speed of your rotation, period of rotation and speed of the tip of your finger
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.
