The change in the angular position of a particle performing circular motion with respect to a reference line in the plane of motion of the particle and passing through the centre of the circle is called the angular displacement .
In the following questions a statement of assertion (A) is followed by a statement of reason ( R). A: Angular displacement is vector quntity only for small values . R: The direction of angular displacement is perpendicular to plane of rotation of object .
A particle moves along a circular path a radius 15 cm with a constant angular acceleration of 4 "rad/s"^(2). If the initial angular speed of the particle was 5 rad/s. Find its angular displacement in 5 seconds.
A uniform rod of mass m and length l is pivoted smoothly at O . A horizontal force acts at the bottom of the rod. a. Find the angular velocity of the rod as the function of angle of rotation theta. b.What is the maximum angular displacement of the rod?
A simple pendulum of Length l and mass (M) is oscillating in a plane about a vertical line between the angular limits -phi "to" +phi . For an angular displacement theta ( lt |phi|) , , the tension in the string T and velocity of the bob V are related as-
