During a 5.1 s time interval, a flywheel with a constant angular acceleration turns through 451 radians and acquires an angular velocity of 136 rad/s. (Assume the flywheel is rotating in the positive direction. Indicate the direction with the signs of your answers.) A.)What is the angular velocity (in rad/s) at the beginning of the 5.1 s? B.)What is the angular acceleration of the flywheel (in rad/s2)?
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.
