An object is acted on by a single nonzero force of magnitudeF. (a) Is it possible for the object to have zero acceleration a?(b) Is it possible for the object to have zero angular acceleration∝? (c) Is it possible for the object to be in mechanicalequilibrium?
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.
