CBSE Class 11 Physics Chapter 5 Laws of Motion NCERT Solutions

Laws of Motion refers to the three physical laws given by Newton that laid the basis for classical mechanics. Also, they define the relationship of a body with the force acting upon it. This NCERT Solutions for Class 11 Physics for Chapter 5 has all the details that you require to realize the concept of the Chapter.

Subtopics covered under NCERT Solutions for Class 11 Physics Chapter 5

5.1 Introduction

This topic describes what we have learned about the laws of motion earlier and what we are going to learn in this chapter.

5.2 Aristotle’s Fallacy

This refers to an argument that does not sound logical. In this topic, the Fallacy theory of Aristotle is described. According to this theory, a body requires an external force to keep it moving.

5.3 The Law of Inertia

This law state that a body of an object does not want to change its state of rest or motion.

5.4 Newton’s First Law of Motion

This law state that an object remains in the state of rest or uniform motion in a straight line unless it is compelled with an external force.

In simple words, objects in motion or rest repel the change in their state of motion.

5.5 Newton’s Second Law of Motion

This law state that the acceleration produced by an object is proportional to the unbalanced force applied to it.

  • Momentum- It refers to the thrust a body produces which is the product of its mass and velocity.
  • Impulse- It refers to the impact force which generates for a short period of time. But it is powerful enough to change the momentum of the object.

5.6 Newton’s Third Law of Motion

According to this law, every action we perform has an opposite and equal reaction. Also, both the action and reaction are equal in magnitude. Moreover, forces always occur in pairs.

5.7 Conservation of Momentum

This law states that the momentum of two objects before and after the happening of the event remains the same. But the objects will move in the direction in which the heavier object was moving. Also, this force is equal to 0.

5.8 Equilibrium of Particle

This refers to the state in which the particle or object is not moving or rotating. Moreover, this requires the sum of movements usually called torque.

5.9 Common Forces in Mechanics

This topic describes the different forces that act on the objects of mechanics.

5.9.1 Friction- It refers to the force that resists the relative motion of an object.

  • Static Friction- the friction that keeps the body at rest.
  • Impending Motion- It means the motion which would take place but does not do anything when force is applied to it.
  • Rolling friction- It states that a rolling round object will not face any friction.

5.10 Circular Motion

This topic describes the movement of an object along with the circumference of a circle. Also, this topic explains the circular motion with the help of an example of a car.

5.11 Solving Problems in Mechanics

These topics define the various ways by which the mechanic’s problems could be solved.
