System of particles and rotational motion class 11 notes. NCERT Solutions for class 11 Physics Chapter 7. A ceiling fan a potters wheel a vehicles wheel are all examples of rotational 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.

Systems of Particles and Rotational Motion Notes Class 11 Physics Chapter 7. This means that the body can only turn around the line which is defined as rotational motion. α d ω d t d ω α d t.

A ceiling fan or a potters wheel these rotating objects are a system of particles that consider the rotational motionIt is the combination of circular motion of large number of particles of a rigid system.

If the relative distance between the particles of a system do not changes on applying force then it called a rigtd body.

Of a body or a system may or may not lie inside the body. Centre of mass and its motion. We come across many objects that follow rotational movements.

The momentum of the CM. Rotation is what you achieve when you constrain a body and fix it along with a straight line. HttpbitlyClass11PhysicsRotationalMotionNotes Free NCERT Solutions.

For rigid bodies centre of mass is independent of the state of the body ie whether it is in rest. The position of centre of mass remains unchanged in pure rotatory motion. Physics Notes Class 11 CHAPTER 7 SYSTEM OF PARTICLES AND ROTATIONAL MOTION Centre of Mass Centre of mass of a system is the point that behaves as whole mass of the system is concentrated at it and all external forces are acting on it.
