Newton's Laws of Motion
Newton's Laws of Motion explain how objects behave when forces act upon them.
Summary
Newton's Laws of Motion explain how objects behave when forces act upon them. The First Law, or law of inertia, states that objects remain at rest or in uniform motion unless an external force acts. The Second Law defines force as mass times acceleration (F = ma), showing how force affects acceleration based on mass. The Third Law states that every action force has an equal and opposite reaction force, meaning forces come in pairs. These laws are fundamental for understanding mechanics and physical interactions in many systems.

Newton's Laws of Motion describe how objects move and interact with forces.
The First Law states that an object at rest will remain at rest, and an object in motion will remain in motion unless acted upon by an external force. This is also known as the law of inertia.
The Second Law states that force is equal to mass times acceleration (F = ma). This means that the acceleration of an object depends on the net force acting on it and its mass.
The Third Law states that for every action, there is an equal and opposite reaction. This explains how forces always occur in pairs.
These laws are fundamental to understanding motion, mechanics, and many physical systems in everyday life.
