📖 1. Inertia and First Law

🔑 Key Concepts & Definitions

• Inertia: The property of an object to resist changes in its state of motion; the tendency to remain at rest or in uniform motion unless acted upon by an external force.
• Newton's First Law: States that an object at rest stays at rest, and an object in motion continues in motion with the same speed and in the same direction unless acted upon by a net external force.
• Net Force: The vector sum of all forces acting on an object; determines whether an object remains at rest or accelerates.
• Equilibrium: A state where the net force on an object is zero, resulting in no change in motion (either at rest or constant velocity).
• Mass: A measure of an object's inertia; the greater the mass, the greater the inertia.
• External Force: A force applied from outside the system that can change an object's motion.
