Aceleration: the rapid movement of a model rocket during the first seconds of a launch; the rate at which velocity changes.
Action/Reaction: Newton's Third Law of Motion
Aerodynamics:The study of the interaction between air and moving objects.
Aerodynamic Stability: Tendency of a rocket to maintain a straight course along the axis of its thrust.
Altitude: The measure of the vertical distance of a rocket from earth.
Angle of Attack: The angle between the relative wind direction and an imaginary line through the center of a flying surface, such as a rocket fin; generally, as the angle of attack increases (raising the forward edge of the surface) so does lift and drag.
Apogee: The highest point reached during a model rocket's flight, measured from the surface of the earth.
Balance Point:The point at which the mass of an object is evenly balanced.
Balsa Wood: A very light, strong wood grown in Ecuador and used in the structure of model rockets
.
Body Tube: A specially wound and treated cardboard or plastic cylinder used to make the fuselage or airframe of a model rocket.
Burnout: The point at which a rocket engine ceases to produce thrust; generally, the point at which all propellant has been burned.
