NCERT Solutions for Class 11 Physics Chapter 5 Laws of Motion are provided in the article below. The branch of physics where we study the motion of a body by considering the cause which is the force which generates the motion is called Dynamics. Newton’s three laws of motion make us understand how objects act when standing still, while moving or when forces behave upon them.
Class 11 Physics Chapter 5 Laws of Motion belongs to Unit 3 which has a weightage of 23 marks along with Unit 2 Kinematics and Unit 3. The Class 11 Physics Chapter 5 NCERT Solutions deals with the concepts of force and Laws of Motion, Non-contact force, Inertia and Mass.

Class 11 Physics Chapter 5 – Concepts Covered
- Newton’s First Law of Motion is referred to as the “Law of Inertia”. The law defines inertia, an inertial frame of reference, and force.
| A body will remain at rest or continue to be in motion with a uniform velocity unless an external force is applied to it. |
- Newton’s Second Law of Motion: When an external force is applied to a body with constant mass, the force produces an acceleration. The acceleration that is produced is directly proportional to the force and then inversely proportional to the mass of the body.
| \(\overrightarrow {F} = K {dP \over dt} = Km \overrightarrow a\) |
- Newton’s Third Law of Motion: To every action, there is an equal and opposite reaction force.
| When body A exerts a force on some other body B, then B exerts an equal and opposite force on A. |
- Linear momentum of a body is the product of the mass and velocity of the body.
| Linear Momentum = mass x velocity |
- Impulse is the product of force and the small-time interval for which the force acts.
| \(Impulse= \int Fdt\) |
