AB r B=A 14/40 Below is a series of diagrams for a thin rod illustrating how the moment of inertia for the same object can change with the placement of the axis of rotation. Notice, that the farther the pivot point is from the object's center of mass, the greater its moment of inertia. Average Angular Speed The average angular speed, ω avg, of a rotating rigid object is the ratio of the angular displacement to the time interval. The instantaneous angular speed is defined as the limit of the average speed as the time interval approaches zero. Units of angular speed are radians/sec. • rad/s or s-1. To calculate the speed and angular velocity of objects. To understand the relationship between linear and angular speed. Radian measure and arc length can be applied to the study of circular motion. In physics the average speed of an object is defined as: $$\text{average speed} = \frac{\text{distance traveled}}{\text{time elapsed}}$$ Rotational Motion's Previous Year Questions with solutions of Physics from JEE Main subject wise and chapter wise with solutions Nov 24, 2011 · Introduction The rotation of a fast moving disc or cylindrical member can set up axial, circumferential and radial stresses.
