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"
