A turntable rotates at 45 rev/min. Calculate the angular velocity of the turntable. A particle on the turntable is located 0.14 m from the center of the rotating turntable. What is the speed of the particle? The particle on the turntable has a mass of 3 g. Calculate the force of friction which keeps it from sliding off.
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.
