NCERT Solutions for Class 11 Physics Chapter 5 Laws Of Motion


NCERT Solutions for Class 11 Physics Chapter 5 Laws Of Motion: Consider the situation that you are traveling in a bus. The bus is moving in a forward direction and suddenly the bus applied the brake. Now definitely you will move in the forward direction. Do you ever think of why this is happening? This is due to the tendency of the person to continue in the state of motion and in Physics we call this tendency as the inertia of motion. There are different types of inertia and you can see a verity of a real-life example of inertia. The concept of inertia is well explained in NCERT Solutions for Class 11 Physics Chapter 5 Laws Of MotionThe chapter Laws of motion deals with Physical and numerical aspects of Newton's laws of motion. 

Now consider an example related to NCERT Solutions for Class 11 Physics Chapter 5. A football moving on the ground stops after some time. The ball stops because of an external force acting on the ball against its motion. This force is the frictional force. Now imagine the case where friction is absent. Whether the ball will stop? That is unless an external force is applied on a body it continues its state of uniform motion along a straight line or continues its state of rest, this is explained by Newton's first laws of motion.

The main topics of the NCERT Solutions for Class 11 Physics Chapter 5 Laws Of Motion are given below.

5.1 Introduction

5.2 Aristotle’s fallacy

5.3 The law of inertia

5.4 Newton’s first law of motion

5.5 Newton’s second law of motion

5.6 Newton’s third law of motion

5.7 Conservation of momentum

5.8 Equilibrium of a particle

To solve the problems of the NCERT Class 11 Physics chapter 5 Laws of Motion it is necessary to understand how to draw a free body diagram. To familiarise with free body diagram it is necessary to practice as many problems as possible. Other coming chapters in Mechanics are the continuation of Laws of Motion.
