Terminology Guide — The Construction Kit

v0.1 · Page 1 of 2

Physics vocabulary is not a random pile of words to be hauled into memory one at a time — it is a construction kit. Nearly every technical term is built from a small set of Greek and Latin parts snapped together. Know that centri- means center and -petal means seeking, and centripetal announces itself — no more confusing centripetal and centrifugal on a test. Memorizing words is linear; learning roots is exponential — thirty parts unlock several hundred words.

The habit that scales

Keep a running roots-and-symbols page at the back of the lab notebook; add to it every time a new prefix, suffix, or unit symbol appears. When you hit an unfamiliar term, break it apart out loud and guess the meaning before you look it up — that retrieval is what fixes the part in memory.

The core roots

PartMeaningExample & what it tells you
kine- / -maticsmotionkinematics — the study of motion without its causes.
dyna-force, powerdynamics — motion and the forces that cause it.
veloc-swiftvelocity — speed with a direction attached.
accel-to hastenacceleration — how fast velocity itself is changing.
grav-heavygravitation — the mutual pull between masses.
centri- / centro-centercentripetal — a force pointing toward the center.
-petal / -fugalseeking / fleeingpetal seeks the center, fugal flees it.
peri- / apo-near / farperigee is an orbit’s nearest point, apogee its farthest.
iso-equal, sameisochronous — each swing takes an equal time.
chrono- / -chron-timechronometer — a clock that keeps precise time.
thermo- / -thermicheatthermometer — anything to do with heat.

How to actually use this

Don’t swallow the table in one sitting. Keep this page open during reading and lab; each time you meet an unfamiliar term, name the parts, guess the meaning, then check. The habit leaves your effort free for the part of physics that actually rewards it — the problem-solving.
