Newton's Second Law — F = ma
受众: Middle School类别: Physics
简介
A block on a frictionless surface is pushed by a constant force. Three scenarios demonstrate that the same force produces less acceleration on heavier blocks and more acceleration on lighter blocks. The formula F = ma is displayed with numerical examples.

Newton's Second Law — F = ma
Description
A block on a frictionless surface is pushed by a constant force. Three scenarios demonstrate that the same force produces less acceleration on heavier blocks and more acceleration on lighter blocks. The formula F = ma is displayed with numerical examples.
Phases
| # | Phase Name | Duration | Description |
|---|---|---|---|
| 1 | Formula Intro | 2s | F = ma displayed prominently |
| 2 | Base Case | 3s | F=10N on m=2kg → a=5 m/s² |
| 3 | Heavier Block | 3s | Same F on m=5kg → a=2 m/s² |
| 4 | Lighter Block | 3s | Same F on m=1kg → a=10 m/s² |
| 5 | Summary | 2s | "More mass → less acceleration" |
