In aviation, there’s ground speed, indicated air speed, true air speed, and calibrated air speed. All pilots have to be familiar with them, but private pilots flying small aircraft at low altitudes generally don’t have to worry too much about CAS. The airspeed numbers are often abbreviated, sometimes with K added for knots (nautical miles per hour) — for example, IAS = indicated air speed, KTAS = knots true air speed.

Bearing - which way you are headed on the surface of Earth. Usually expressed in degrees - 0 = north, 90 degrees = East, 180 is south, and 270 degrees = west.
Knots - Nautical miles per hour
Speed - distance divided by time - usually stated as miles per hour or miles per second.
vector - direction in space
course - line tht describes the shorted route
Chart, Map, Atlas, or uranometria, - model of the space flattened to 2 dimensions for ease of study on a flat surface
