Important topics for DC Pandey Mechanics Part 1 Solutions Chapter 7: Circular Motion
Dynamics of Circular Motion
In DC Pandey Mechanics Part 1 Circular Motion Chapter, you will learn that when a particle moves with a constant speed in a circle its motion is known as uniform circular motion.
A resultant of non-zero force acts on the particle when it is in a uniform circular motion. You will get to know that the reason behind this occurrence is because the particle that moves in a circular direction is accelerated despite the speed of that particle being constant. Change in direction of the velocity vector acts as the main reason behind this occurrence. The tangential acceleration in case of a uniform circular motion can be null.
When the acceleration of the particle is towards the centre, its magnitude is expressed as v2 / r. Here v denotes the speed of the particle and r stands for the radius of the circle.
In such a case the direction of the resultant force is towards the centre and the magnitude can be expressed as F = ma. Here m stands for the mass of the particle and a stands for acceleration.
In this chapter, you will also encounter the concept of a conical pendulum and its mechanism. When a small particle of, let’s say, mass ‘m’ is suspended by a string which is whirled in a horizontal circle, the entire arrangement is recognized as a conical pendulum. The vertical component of a conical pendulum is known as the vertical component of tension and it balances the weight of the particle while the horizontal component works at providing the necessary centripetal force. You will also learn about the pseudo force which is addressed as the centrifugal force and the application of Newton’s law on it.
