A hollow sphere, a solid sphere, and a solid disk, all of mass M= 1 kg and radius R= 5 cm sit at rest atthe top of an incline of angle θ above the horizontal. If all three objects are released from rest a distance d= 1 m along the incline from its end, which object will reach the bottom of the incline first, second, and third? How long does it take the first object to reach the bottom?
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.
