October Sky Vocabulary
Theodolite, a precision instrument having a telescopic sight for establishing horizontal and sometimes vertical angles.
Originated from modern Latin in the late 16th century.
Example: Elijah used his theodolite to calculate a precise measurement of height for his rocket.
Arc, something curved in shape
Originated in 1350-1400 from Middle English, and Latin
Example: The arc of the rocket's path was quite thin compared to his other runs with the different design.
Research Vocabulary
Thrust, the propulsive force of a jet or rocket engine.
Originated in 1125-1175, Middle English and Old Norse
Example: Our rocket needed more thrust if it was going to climb any higher.
Propellant, a substance or object that causes something to move or to be driven forward or outward.
Originated in 1915-1920, propel + ant
Example: To increase our height, we would need more propellant.
Physics Vocabulary
Velocity, the speed of something in a given direction
Originated in 1540-1550, Latin
Example: Velocity was directly related to the amount of fuel we bestowed on the vehicle.
Acceleration, the rate of change in velocity
Originated from Latin in 1525-1535
Example: We needed the acceleration to increase by at least a fourth if we were going to have any confidence in our rocket.
