What do the first two laws of motion describe?

The first two laws of motion are fundamental principles articulated by Sir Isaac Newton. Newton’s First Law, often called the law of inertia, states that an object at rest remains at rest, and an object in motion continues in a straight line at a constant speed unless acted upon by a net external force. Newton’s Second Law establishes the relationship between force, mass, and acceleration, stating that the force acting on an object is equal to the mass of the object multiplied by its acceleration. These laws form the basis for understanding the dynamics of motion, providing insights into how objects move and respond to forces in classical mechanics.
