Angular Momentum Formula
The Formula
When to use: A spinning skater pulling their arms in spins faster — they're conserving angular momentum.
Quick Example
What This Formula Means
The rotational equivalent of linear momentum — a measure of how much rotational motion an object has.
A spinning skater pulling their arms in spins faster — they're conserving angular momentum.
Why This Formula Matters
Explains gyroscopes, spinning tops, planetary orbits, and why ice skaters spin faster with arms in.
