Newton's First Law: Law of Inertia
Cliff Notes
I. Inertia
A. Inertia: what makes an object resist a change in motion
B. More mass = more inertia
C. Examples
1. Football player blockers are bigger (have more mass-->more inertia) because they don't want to move
Wide receivers are smaller (less mass-->less inertia) because they need to move quickly
2. Cars are smaller than buses (have less mass-->less inertia), so they can turn more quickly
3. Long boards are harder to maneuver than short boards (have more mass-->more inertia), so it's harder
to turn them
II. Newton's First Law: Law of Inertia
A. Objects in a state of rest, or in a state of motion at constant speed in a straight line, will continue in that
state unless a force acts on it
