Miacademy & MiaPrep Learning Channel
Guided Notes
Key concepts students will learn:
- •
Inertia is the tendency of an object to resist changes in its velocity.
- •
Newton's first law of motion, also known as the law of inertia, states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an outside force.
- •
The amount of inertia an object has depends on its mass; the more mass, the more inertia.
