Laws of Motion
The laws of motion are a fundamental part of classical physics formulated by Sir Isaac Newton. They describe the relationship between the motion of an object and the forces acting upon it. The laws of motion consist of three principles, known as Newton’s laws of motion:
- Newton’s First Law of Motion (Law of Inertia):
- An object at rest will remain at rest, and an object in motion will continue in motion with a constant velocity unless acted upon by an external force.
- In simpler terms, objects tend to resist changes in their state of motion.
- Newton’s Second Law of Motion:
- The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
- Mathematically, it can be expressed as F = ma, where F is the net force applied, m is the mass of the object, and a is the acceleration produced.
- Newton’s Third Law of Motion:
- For every action, there is an equal and opposite reaction.
- Whenever an object exerts a force on another object, the second object exerts an equal and opposite force on the first object.
These laws provide a foundation for understanding the motion of objects and the forces that govern their behavior. They have wide applications in various fields, including engineering, physics, and even everyday life.

How is Required NEET CHEMISTRY SYLLABUS Laws of Motion
The laws of motion, formulated by Sir Isaac Newton, describe the fundamental principles governing the motion of objects. These laws provide a framework for understanding how forces affect the motion of objects and are crucial in the field of physics. Let’s explore the laws of motion in more detail:
- Newton’s First Law of Motion (Law of Inertia):
- The first law states that an object at rest will stay at rest, and an object in motion will continue to move at a constant velocity in a straight line unless acted upon by an external force.
- In simpler terms, objects tend to resist changes in their state of motion. If no net force acts on an object, it will maintain its current state of motion.
- Newton’s Second Law of Motion:
- The second law relates the force acting on an object to its mass and acceleration.
- Mathematically, the second law is expressed as F = ma, where F represents the net force applied to an object, m is the mass of the object, and a is the acceleration produced.
- According to this law, when a force acts on an object, it causes the object to accelerate in the direction of the force. The greater the force applied, the greater the resulting acceleration, and the greater the mass of the object, the smaller the acceleration for a given force.
- Newton’s Third Law of Motion:
- The third law states that for every action, there is an equal and opposite reaction.
- When one object exerts a force on a second object, the second object exerts a force of equal magnitude but in the opposite direction on the first object.
- This law highlights that forces always occur in pairs and act on different objects. The forces are equal in magnitude but opposite in direction.
These laws of motion provide a foundation for understanding the behavior of objects in motion and the forces that govern their interactions. They have extensive applications in various fields, including physics, engineering, and even everyday experiences.
Case Study on NEET CHEMISTRY SYLLABUS Laws of Motion
A Car Accelerating on a Straight Road
Scenario: Imagine a car traveling along a straight road. The driver presses the accelerator pedal, increasing the engine’s power and causing the car to accelerate.
Application of Newton’s Laws of Motion:
- Newton’s First Law of Motion (Law of Inertia): According to the first law, an object at rest will remain at rest, and an object in motion will continue moving at a constant velocity unless acted upon by an external force. In this case, before the driver presses the accelerator, the car is either stationary or moving at a constant speed. Due to the law of inertia, the car tends to maintain its state of motion.
- Newton’s Second Law of Motion: The second law relates the force, mass, and acceleration of an object. When the driver presses the accelerator pedal, it applies a force to the car. According to Newton’s second law (F = ma), the acceleration of the car is directly proportional to the net force applied and inversely proportional to its mass. Therefore, the greater the force applied, the greater the acceleration experienced by the car.
- Newton’s Third Law of Motion: According to the third law, for every action, there is an equal and opposite reaction. When the car’s engine generates a forward force, the tires of the car exert an equal and opposite force on the road, referred to as the reaction force. This reaction force enables the car to move forward.
Throughout this case study, all three laws of motion are at play. The first law explains the initial state of motion of the car, the second law relates the force applied to the car’s acceleration, and the third law describes the reaction force from the tires pushing against the road.
It’s important to note that this case study simplifies the real-world scenario, as it disregards factors like friction, air resistance, and other external forces that may affect the car’s motion. Nevertheless, Newton’s laws of motion provide a fundamental understanding of the principles governing the motion of objects.
