The force that attracts a body toward the center of the earth
Gravity
An aircraft similar to an airplane that has no engine.
Glider
A push or pull on an object.
Force
Resulting quantity of something. For example, the quantity of food produced from crop growth.
The path of an object moving through space.
Trajectory
The force that makes it difficult for one object to slide along the surface of another
Friction
The main body of an aircraft.
Fuselage
Newton's 2nd Law
F=MA
A circular or elliptical path followed by one body as it revolves around another body.
Orbit
An object in orbit around a planet or moon in space. An artificial satellite is a human made object that has intentionally been placed in orbit.
Satellite
The force of gravity that pulls objects downward
Weight
The upward force that enables an aircraft to raise off the ground and remain in flight.
Lift
Newton's 3rd Law
For every action there is an equal and opposite reaction.
The means by which aircraft and spacecraft are pushed forward.
Propulsion
A state of very weak gravity.
Microgravity
A working model used to test a design concept by making observations and necessary adjustments.
Prototype
Up and down motion of the wings of the aircraft.
Roll
Newton's First Law
An object at rest will remain at rest unless acted on by any unbalanced force. An object in motion continues in motion
A measure of health; the maximum amount of oxygen the body can use during exercise.
Aerobic Capacity
Discarded objects, trash, and other man-made debris left in orbit during space flights.
Working together on a common purpose.
Collaboration
The part on an airplane that raises and lowers the wings, causing the aircraft to roll.
Aileron
Resistance of air against the forward movement of an airplane or rocket.
Drag
The process of burning something.
Combustion
The thick layer of gasses surrounding Earth and other planets.
Atmosphere
