Radian measure and arc length can be applied to the study of circular motion. It is possible to analyse circular motion in terms of this ‘linear’ speed but there are occasions when this causes difficulties. Circular motion does not have to be at a constant speed. 3] Lesson 9: Uniform Circular Motion [9. It can be uniform, with constant angular rate of rotation (and constant speed), or non-uniform with a changing rate of rotation. Background material for circular motion Because the direction changes in circular motion, the velocity changes, even if the speed is constant. We first calculate the centripetal force, by adjusting the radius and weighing the masses. Problem Name Rotational vs. These can be used to make predictions but do not explain why the observed phenomena exist. The distance of the body from the axis of rotation remains constant at all times. Circular Motion HC Verma Concepts of Physics Solutions Chapter 7. Note that, unlike speed, the linear velocity of an object in circular motion is constantly changing because it is always changing direction. Linear velocity, v, of an object is its instantaneous velocity at any point in its circular path. Centripetal Force. 3] Lesson 9: Uniform Circular Motion [9. The acceleration—centripetal acceleration—toward the centre of the circle can be explained using the definition of acceleration (rate of change of velocity) where the direction of the acceleration is.
