It is given by . Axis of Rotation. For a system of particles, the centre of mass is defined as that point where the entire mass of the system is imagined to be concentrated, for consideration of its translational motion. Torque acting on a particle is defined as the product of the magnitude of the force acting on the particle and the perpendicular distance of the application of force from the axis of rotation of the particle. • Vector Product or Cross Product of two vectors • Moment of Inertia If all the external forces acting on the body/system of bodies were to be applied at the centre of mass, the state of rest/ motion of the body/system of bodies shall remain unaffected. Some Basic Concepts of Chemistry; ... System of Particles & Rotational Motion; 08.Gravitation; 09. 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.

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., 01. • Centre of Mass Revision Notes on Circular& Rotational Motion Circular Motion:-Uniform Circular Motion:-Circular motion is said to the uniform if the speed of the particle (along the circular path) remains constant. Physicswallah Typed Notes Click here Physicswallah HandWritten Notes- NLM & Friction Click here Chapter Formula Click here HC Verma Solutions Laws Of Motion â¦ 01. • Angular Momentum Law of Motion Class 11 Notes Physics Chapter 5 â¢ Dynamics is the branch of physics in which we study the motion of a body by taking into consideration the â¦ This point is [â¦] The circular paths of all the point masses have a common centre. For complete equilibrium, both these conditions must be fulfilled. The rotational inertia of a rigid body is referred to as its moment of inertia. • Torque 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 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. For translational equilibrium, the vector sum of all the forces acting on a body must be zero. System of Particles and Rotational Motion Download in PDF. Chapter 5.
