Conservation of Momentum
受眾: High School類別: Physics
簡介
Two collision scenarios on a frictionless surface demonstrate momentum conservation. An elastic collision shows ball 1 stopping and ball 2 moving on. An inelastic collision shows the balls sticking together. Momentum vectors p = mv are shown before and after each collision.

Conservation of Momentum
Description
Two collision scenarios on a frictionless surface demonstrate momentum conservation. An elastic collision shows ball 1 stopping and ball 2 moving on. An inelastic collision shows the balls sticking together. Momentum vectors p = mv are shown before and after each collision.
Phases
| # | Phase Name | Duration | Description |
|---|---|---|---|
| 1 | Formula Intro | 1.5s | p = mv and p_total = const displayed |
| 2 | Elastic Collision | 4s | Ball 1 hits stationary ball 2; 1 stops, 2 moves |
| 3 | Momentum Check | 2s | Before/after momentum arrows compared |
| 4 | Inelastic Collision | 4s | Balls stick together and move at half speed |
| 5 | Summary | 2s | Conservation law stated |
