Newton's laws laid the foundation for classical mechanics and are still used today to describe the behavior of objects in motion.

Newton's three laws of motion are as follows:

1. First Law (Law of Inertia):

   • An object at rest will remain at rest, and an object in motion will continue in motion with constant velocity (constant speed in a straight line), unless acted upon by an external force.
   • In simpler terms, this law asserts that objects tend to maintain their state of motion unless an external force changes that state.

2. Second Law (Law of Acceleration):

   • The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This relationship is expressed by the equation �=��F=ma, where �F is the net force applied to the object, �m is the mass of the object, and �a is the acceleration produced.
   • This law indicates that the greater the force applied to an object, the greater its acceleration will be, and the more massive the object, the less it will accelerate for a given force.

3. Third Law (Action-Reaction Law):

   • For every action, there is an equal and opposite reaction. This means that whenever one object exerts a force on a second object, the second object exerts an equal and opposite force back on the first object.
   • In practical terms, this law explains phenomena such as the propulsion of a rocket, where the rocket expels gas in one direction (action), and in reaction, the rocket moves in the opposite direction.
