- Newton's first law (in my own words): If no unbalanced (net) force acts on an object, it will keep doing whatever it is doing — staying at rest or moving in a straight line at constant speed. In other words, objects resist changes to their state of motion (this resistance is called inertia), and the law is true in inertial (non-accelerating) reference frames.

- Newton's second law (equation): ΣF = m a
(the vector sum of all forces on an object equals its mass times its acceleration).

- How mass differs from weight:
- Mass is an intrinsic property of matter that measures how much matter (and inertia) an object has. It is constant for an object regardless of location. Units: kilograms (kg).
- Weight is the force exerted on that mass by gravity. It depends on the local gravitational field strength: W = m g. Units: newtons (N). Weight changes with location (e.g., it is less on the Moon than on Earth) while mass does not.
