A pulley with radius of 12 cm pulls a chain as it rotates. If the chain is moving at 4.2 cm per second, what is the angular velocity of the pulley in degrees per second? Round your answer to the nearest tenth.
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.
