The rotor of a lab centrifuge has moment of inertia 0.0113 kg m^2 and spins at 1470 rad/s. If a brake exerts a perpendicular force of 16 N at 0.075 m from the spin axis, what is the magnitude of the angular acceleration?
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.
