Astronauts are trained for take-off in a high-speed centrifuge of 5.9 m radius that spins in the horizontal plane.(a) What is the average angular speed required for the astronauts to train at 3.5 g's? (b) How fast (linear speed) are they moving at that time? (c) What is the direction of the astronaut's apparent weight? W = r̂ + t̂ + ẑ
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.
