## Summary of NCERT Solutions for Class 11 Physics Chapter 5 Laws of Motion

NCERT Solutions for Class 11 Physics Chapter 5 Laws of Motion introduces you to various topics of the chapter. Learning concepts of the laws of motion is important because it is implemented in almost everything. It is important to understand all the concepts of the chapter before solving the exercises given in the NCERT book. Here are some important topics you will come across while revising the chapter:

Aristotle’s Fallacy

Aristotle’s fallacy states that to keep a body in uniform motion, there’s a need for an external force. It also means that the body would continue to be in motion while an external force is applied to it.

The Law of Inertia

The Law of Inertia deals with the property of an object to stay at rest or in motion. It states that the property of an object cannot change its state of rest or uniform motion along a straight line without the help of an external force. Inertia is of three types, namely Inertia of Rest, Inertia of Motion and Inertia of Direction.

Momentum

Momentum is referred to the total amount of motion that is present in the body of an object.

Newton’s First Law of Motion

It states that a body continues to be in its state of rest or in uniform motion along a straight line unless an external force is applied on it. It is the same as the Law of Inertia.

Newton’s Second Law of Motion

It states that the acceleration of an object is dependent on the two variables- the mass of the object and the net force that acts upon it. As the force acting upon the object is increased, so is the acceleration of the object increased.

Newton’s Third Law of Motion

This law states that every action has an equal and opposite reaction.

Force

Force can be classified into two types- contact forces and action at a distance force. Anything that causes an object to undergo any kind of motion is known as force.

Friction

When one body moves or tries to move over another body it is called friction. Friction is called an opposing force. Some types of friction include kinetic friction, static friction and limiting friction.

Circular Motion

As the name suggests, circular motion deals with the movement of an object along the circumference of a circle or a circular path.
