DEFINITIONS
AIR
The invisible gaseous substance surrounding the earth, a mixture mainly of oxygen and nitrogen.
GLIDE

Example: a few glondalas glided past
WHAT ARE THE FOUR FORCES OF FLIGHT
WEIGHT THRUST
LIFT DRAG
TRUE OR FALSE?
Birds and Insects are the only living things that can fly
TRUE
birds and insects are the only living things that can fly
LIFT
Raise to a higher position or level
Example he lifted his trophy over his head
AERODYNAMICS
Is the study of the motion of air, particularly when affected by a solid object such as an airplane win. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics and is an important domain of study in aeronautics

COMPRESS
To press or squeeze together
To reduce in size quantity or volume as if by squeezing compress a computer file
WEIGHT
In science and engineering, the weight of an object is a quantity associated with the gravitational force exerted on the object by other objects in its environment, although there is some variation and debate as to the exact definition
