Ideally, a rigid body is one for which the distances between different particles of the body do not change, even though there are forces on them. 2. A rigid body fixed at one point or along a line can have only rotational motion. A rigid body not fixed in some way can have either pure translational motion or a combination of translational and rotational motions. 3. In rotation about a fixed axis, every particle of the rigid body moves in a circle which lies in a plane perpendicular to the axis and has its centre on the axis. Every Point in the rotating rigid body has the same angular velocity at any instant of time. 4. In pure translation, every particle of the body moves with the same velocity at any instant of time. 5. Angular velocity is a vector. Its magnitude is ω = dθ/dt and it is directed along the axis of rotation. For rotation about a fixed axis, this vector ω has a fixed direction. 6. The vector or cross product of two vector a and b is a vector written as a×b. The magnitude of this vector is absinθ and its direction is given by the right handed screw or the right hand rule. 7. The linear velocity of a particle of a rigid body rotating about a fixed axis is given by v = ω × r, where r is the position vector of the particle with respect to an origin along the fixed axis. The relation applies even to more general rotation of a rigid body with one point fixed. In that case r is the position vector of the particle with respect to the fixed point taken as the origin. 8. The centre of mass of a system of n particles is defined as the point whose position vector is R=∑mi ri/M 9. Velocity of the centre of mass of a system of particles is given by V = P/M, where P is the linear momentum of the system. The centre of mass moves as if all the mass of the system is concentrated at this point and all the external forces act at it. If the total external force on the system is zero, then the total linear momentum of the system is constant. ________________ system of particles and rotational motion class 11 one shot system of particles and rotational motion class 11 neet system of particles and rotational motion in tamil system of particles and rotational motion tamanna chaudhary system of particles and rotational motion class 11 vedantu tamil system of particles and rotational motion explanation in tamil system of particles and rotational motion vedantu tamil system of particles and rotational motion class 11 ncert in tamil 11th ncert physics system of particles and rotational motion in tamil class 11th physics system of particles and rotational motion in tamil cbse class 11 physics system of particles and rotational motion in tamil system of particles and rotational motion class 11 problems tamil ch 6 system of particles and rotational motion class 11 in tamil system of particles and rotational motion class 11 vedantu neet tamil system of particles and rotational motion class 11 important questions in tamil
