Rotational Motion Part 1 (Introduction) Rotational Motion Part 2 (Rotation about fixed axis) Two equal and opposite forces acting on a body but having different lines of action, form a couple. System of Particles and Rotational Motion Class 11 is one of the important chapters when it comes to understanding the basics of circular motion. A rigid body performs a pure rotational motion, if each particle of the body moves in a circle, and the centre of all the circles lie on a straight line called the axes of rotation. It is given by . Class-XI. • Axis of Rotation According to this theorem, the moment of inertia I of the body about a perpendicular axis is equal to the sum of moments of inertia of the body about two axes at right angles to each other in the plane of the body and intersecting at a point where the perpendicular axis passes, i.e., Chapter Wise CBSE Quick Revision Notes and Key Points for Class 11 Physics Notes Pdf free download was designed by expert teachers from the latest edition of NCERT books to get good marks in board exams. PHYSICAL WORLD . The centre of mass of a two- particle system always lies on the line joining the two particles and is somewhere in between the particles. N.C.E.R.T Chapter 05 Click here Assignments Click here Answers of assignment are given at the end of each assignment with complete solutions. This point is […] MOTION IN A PLANE part-1. If we consider that the whole mass of the body is concentrated at a distance K from the axis of rotation, then moment of inertia I can be expressed as I = MK2 • Centre of Mass A rigid body is said to be rotating if every point mass that makes it up, describes a circular path of a different radius but the same angular speed. • Vector Product or Cross Product of two vectors Chemistry-XI. JEE Main 2020 Physics Syllabus. Students have to answer around 25 questions carrying 4 marks each. The distances between all pairs of particles of such a body do not change. Click here ( Short Notes) – Download Click Here Com… Physics Notes Class 11 CHAPTER 5 LAWS OF MOTION Inertia The property of an object by virtue of which it cannot change its state of rest or of uniform motion along a straight line its own, is called inertia. Master Class 11 Physics And Be Successful in exams. The distance of a point in a body from the axis of rotation, at which if whole of the mass of the body were supposed to be concentrated, its moment of inertia about the axis of rotation would be the same as that determined by the actual distribution of mass of the body is called radius of gyration. The circular paths of all the point masses have a common centre.
