Newton's Second Law β€” F = ma

Audience: Middle SchoolCategory: Physics

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.

Newton's Second Law β€” 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 β†’ a=5 m/sΒ²
3 Heavier Block 3s Same F on m=5kg β†’ a=2 m/sΒ²
4 Lighter Block 3s Same F on m=1kg β†’ a=10 m/sΒ²
5 Summary 2s "More mass β†’ less acceleration"
