What is Newton's First and Second Law?

[justx007]

I already learned about Newton's Third Law but nowhere in my reference book can I find Newton's First and Second Law. Surely there must be the First and Second Law before the Third Law is taught.
What is Newton's First and Second Law about ?

Newton's First Law, also known as the Law of Inertia, states that an object will remain at rest or in motion with a constant velocity unless acted upon by an external force. This means that an object will continue to move in a straight line at a constant speed, or remain at rest, unless a force is applied to change its motion.

Newton's Second Law, also known as the Law of Acceleration, states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This means that the greater the force applied to an object, the greater its acceleration will be, and the more massive an object is, the less it will accelerate for a given force.

These two laws are fundamental principles in classical mechanics and are essential for understanding the behavior of objects in motion. They were developed by Sir Isaac Newton in the 17th century and laid the foundation for our modern understanding of motion and forces. It is important to learn about these laws before Newton's Third Law because they provide the basic framework for understanding how forces and motion work in the physical world.
