The botany forceexperienced by an object is exactly equal to the weight of the displaced
Archimedes
The tendency of a solid object to float whenplaced in a fluid
Buoyancy
One device used to measure the specific gravity of a liquid
Hydrometer
The submarine is completely underwater not not sinking
Neutral buoyancy
Pressure exerted by a moving fluid decreased as the fluids speed increases
Bernoulli’s principal
A structure that changes the flow of air to produce a force
airfoil
The upward force
Lift
The force that projects a plane forward through the air
Thrust
The force hat tends to slow an object
Drag
Usually located on small winglike horizontal stabilizers near the rear of the aircraft
Elevators
Tilts the plane from side to side
Ailerons
Located on the beeticka stabilizer
Controls angle left or right
Rudder
Increase the wing area and adjust the airfoil shape to provide more lift
Flaps
Increases lift at slow speeds by altering the airfoil
Slats
The science of shaping objects to allow the smooth flow of fluids around them and reduce drag
