John wanted to measure the objects angular speed at the bottom of the hill. He built the inclined frictionless ramp of height d, release the object from the top, and measure the angular speed at the Bottom. First, John released a hollow sphere [Ip(2/3) mr^2] from the rest. The diameter and the mass of the sphere were 317 cm and 45.2 kg, respectively. How much was the angular speed John measures at the bottom of the incline he built. Tip: the object rotates down the incline without slipping. Use following values: d=3.57 m and g=9.80 m/s^2
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.
