## Why it matters

Physics is expressed in mathematics; fluency in these tools determines how smoothly every later physics topic is learned.

## Where it is used

Every physical calculation: kinematics, forces, fields, waves, energies; also engineering and data analysis toolkits.

## How you know you have learned it

Complete 3 independent examples correctly + explain common failure modes.
