Newton's First Law of Motion: Mass and Inertia
Professor Dave Explains
Guided Notes
Key concepts students will learn:
- •
Newton's first law states that an object at rest will stay at rest, and an object in motion will stay in motion with constant velocity unless acted upon by an external force.
- •
Inertia is the capacity of an object to resist changes in motion, and it is proportional to an object's mass.
- •
A net force of zero means there is no acceleration, so the object preserves its state of motion, whether at rest or moving with constant velocity.
