Angular acceleration is the rate of change of angular velocity, which is the rate at which an object rotates around a fixed axis. It is measured in radians per second squared (rad/s²) or revolutions per second squared (rev/s²).
Angular acceleration can be calculated by dividing the change in angular velocity by the change in time. The formula is: α = (ω₂ - ω₁) / (t₂ - t₁), where α is the angular acceleration, ω is the angular velocity, and t is time.
The unit of measurement for angular acceleration is radians per second squared (rad/s²) or revolutions per second squared (rev/s²).
Solving 500-700rev/sec in 30sec means finding the angular acceleration of an object that rotates at a speed of 500-700 revolutions per second in a time span of 30 seconds.
Angular acceleration has applications in various fields such as physics, engineering, and astronomy. It is used to study the motion of objects in circular motion, such as the rotation of planets, the movement of gears in machines, and the spinning of a roller coaster. It is also important in understanding the stability and control of aircraft and spacecraft.
