Newton's Laws of Motion

First Law (Law of Inertia)

An object at rest will remain at rest, and an object in motion will continue to move with a constant velocity, unless acted upon by an external force.
Inertia is the tendency of an object to resist changes in its motion.
This law applies to all objects, big or small, and is a fundamental concept in understanding motion.

Second Law (F = ma)

Force (F) is equal to the mass (m) of an object multiplied by its acceleration (a).
F = ma
The more massive an object is, the more force is required to produce a given acceleration.
The greater the force applied to an object, the greater its resulting acceleration.

Third Law (Action and Reaction)

For every action, there is an equal and opposite reaction.
When two objects interact, they apply forces to one another that are equal in magnitude and opposite in direction.
Examples:
- When you push on a wall, the wall pushes back on you with the same force.
- When a car accelerates forward, the ground exerts an equal and opposite force backward on the car.

Key Concepts

Force: A push or pull that causes an object to change its motion.
Mass: A measure of an object's resistance to changes in its motion.
Acceleration: The rate of change of an object's velocity.
Inertia: The tendency of an object to resist changes in its motion.
