A pulley, with a rotational inertia of 1.0*10-3 kgm2 about its axle and a radius of 10 cm,is acted on by a force applied tangentially at its rim.The force magnitude varies in time as F=0.50t+0.30t2, with F in newtons and t in seconds.The pulley is initially at rest.At t=3.0 s what are its (a) angular acceleration and (b) angular speed?
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.
