3. Laws of Motion
The chapter delves into the principles of motion influenced by forces, primarily focusing on Newton's Laws of Motion. It explains the concepts of force, inertia, momentum, and impulse, illustrating their applications in real life. The understanding of these laws is essential for comprehending the dynamics of motion in various scenarios.

What we have learnt
- Motion is influenced by forces and can be analyzed through Newton's Laws of Motion.
- The three laws describe how objects behave under certain conditions of force and motion.
- Inertia varies with the type of movement or rest an object experiences.
Key Concepts
- -- Force
- A push or pull that results in a change in the state of an object's motion.
- -- Inertia
- The property of an object to remain at rest or to move at a constant velocity unless acted upon by a force.
- -- Momentum
- The product of an object's mass and velocity, representing the quantity of motion an object has.
- -- Impulse
- The change in momentum of an object when a force is applied over a period of time.
