Newton's First Law — Inertia
受眾: Middle School類別: Physics
簡介
A ball on a surface gradually stops due to friction; in frictionless space it rolls forever at constant speed. A car-braking inertia demo shows a passenger lurching forward. Label: "No net force = no change in motion."

Newton's First Law — Inertia
Description
A ball on a surface gradually stops due to friction; in frictionless space it rolls forever at constant speed. A car-braking inertia demo shows a passenger lurching forward. Label: "No net force = no change in motion."
Phases
| # | Phase Name | Duration | Description |
|---|---|---|---|
| 1 | Title | 1.5s | Title and Newton's 1st law text |
| 2 | With Friction | 3s | Ball rolls, friction arrow shown, ball decelerates |
| 3 | Without Friction | 3s | Ball in space keeps moving at same speed forever |
| 4 | Car Braking | 3s | Car stops, passenger lurches forward |
| 5 | Key Label | 2s | "No net force = no change in motion" |
