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"
