Root Explanation

Ultracentrifuge → It is formed from "ultra-" (meaning beyond) and "centrifuge" (from Latin "centrum" meaning center and "fugere" meaning to flee). The word describes a device that spins substances at high speeds to separate components by moving them beyond the center of rotation.

Memory Tip

Think of 'beyond' ('ultra-') the center ('centrum') where substances 'flee' ('fugere') from each other due to the force of spinning — that's how an ultracentrifuge separates materials.
