Science

1. states that as air moves around an object, it creates different pressures on that object and that faster air means less pressure and slower air means more pressure.
6. the physical force exerted on an object.
8. a propulsive force of a plane or jet.
9. the SI unit of pressure, equal to one newton per square meter.
10. matter that flows, liquid or gas
12. a device that expells gas in one direction in order to move in the other direction
13. an upward force that counteracts the force of gravity.

2. for every action on an object, there is an equal and opposite reaction on that object.
3. the minimum velocity at which a body must move to maintain a given orbit.
4. the lowest velocity that a body must have in order to escape the gravitational attraction of a particular planet or other objects.
5. force that pulls objects toward each other.
7. an instrument measuring atmospheric pressure.
11. force that opposes an aircraft's motion through the air.
