A sedan moves relative to the road at 20mph. A sports car is catching up with it by driving at 50mph (relative to the road) Is the sedan's trunk to the rear of its hood a) in the earth's frame? b) in the sport car's frame? c) in the sedan's frame?
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.
