What is system of particles and rotational motion?
The combination of rotational motion and the translational motion of a rigid body is known as rolling motion. According to the law of conservation of angular momentum, if there is no external couple acting, the total angular momentum of a rigid body or a system of particles is conserved.
How do you read motion in a straight line?
If a body travels in a straight line and covers an equal amount of distance in an equal interval of time, it is said to have uniform motion. In simple words, a body is said to have uniform acceleration if the rate of change of its velocity remains constant.
Which is the third chapter of physics class 11?

When a rigid body is in motion few particles of the body remains at rest?
When a rigid body is in motion, few particles of the body remain at rest at all times. What kind of motion is the rigid body having? Particles on the axis of rotation of a rotating body remain at rest.
Which topics comes under rotational motion?
What are the main topics for rotational motion
- Moment of Inertia.
- Torque.
- Kinetic Energy of Rotation.
- Work and Rotational Energy.
- Angular Momentum.
- Rolling as Rotation.
Why is there a need to study motion in straight lines?
The study of motion in a straight line should be included in any introductory course in calculus. It serves both as a context for understanding the basic concepts of calculus and as an important application of calculus.
Is motion in a straight line kinematics?
Kinematics is the description of motion without considering its causes. In this chapter, it is limited to motion along a straight line, called one-dimensional motion.
Is motion in a straight line important for NEET?
Important notes of Physics for NEET, JEE for Motion in a Straight line are useful for all aspirants preparing for entrance exams including JEE, NEET. Important notes are also helpful for revision when you have less time and have to study many topics.
Can a rigid body be elastic?
Rigid body is actually a system of particles and the word rigid signifies that their shouldn’t be any relative displacement between any two particles in this system of particles. In this sense a rigid body can never be elastic.
Why it is necessary to assume a body as perfectly rigid for the Study of statics?
Statics assumes that the bodies with which it deals are perfectly rigid. If more than three unknown forces exist, it means that there are more components in the structure or machine than are required to support the applied loads or that there are more restraints than are needed to keep the body from moving.
What is ncncert Chapter 7 Class 11 Physics?
NCERT Solutions for Class 11 Physics Chapter 7 System of Particles and Rotational Motion is an important study material that will help you understand the topic more deeply thereby guiding you in scoring good marks in the Class 11 first term exam and entrance examinations.
What is the system of particles and rotational motion chapter about?
The system of particles and rotational motion chapter includes various important topics that will enhance the knowledge of rigid body motion with illustrations from the objects we witness to observe in our everyday life.
What are the key points of the chapter physics of motion?
Some of the key points of the chapter are as follows: Determining the motion of rigid bodies, the centre of mass of the system. Finding the density of the body depending upon the type of distribution of particles. The distribution of the particles will be either discrete or continuous systems.
What do you learn in the first chapter of Physics?
Hence, the first topic covered is Vector Physics. (Addition, Subtraction, and Multiplication of Vectors, and a few more). As a simple case of motion in a plane, the projectile motion is discussed. Uniform circular motion is also discussed in this chapter. Study the concepts of vectors and the subtopics.
