An astronaut is inside a centrifuge that has a radius of 10 m. The astronaut starts from rest and experiences a constant angular acceleration for 10 seconds. After the 10 seconds, the astronaut is experiencing 10g, meaning that the centripetal acceleration is ac=98ms2ac=98ms2. The angular displacement of the astronaut during the 10 seconds was
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.
