Weight is the force. It acts in a downward direction, toward the center of the Earth.
GRAVITY
THRUST
DRAG
LIFT
Select the two that apply...
LIFT is:
A force that acts at a right angle to the direction of motion through the air.
Created by the difference in air pressure.
The force that propels a flying machine.
Which is the CORRECT definition of THRUST?
The invisible gaseous substance surrounding the Earth.
It acts in a downward direction, toward the center of the Earth.
Thrust is the force that propels a flying machine in the direction of motion.
Select the 2 that apply...
DRAG is:
The force that acts at a right angle to the direction of motion through the air.
The force that acts opposite to the direction of motion.
The force that moves something forward.
Caused by friction and differences in air pressure.
Select the two that are true about
PROPULSION
The force that moves something forward.
It acts opposite to the direction of motion.
It acts at a right angle to the direction of motion through the air.
A propulsion system is an engine that produces thrust to push an object, such as an airplane or rocket, forward.
_ _ _ _ is the force that acts at a right angle to the direction of motion through the air. It is created by differences in air pressure.
(a)
_ _ _ _ _ _ is the force that propels a flying machine in the direction of motion.
(a)
_ _ _ _ is the force that acts opposite to the direction of thrust. It is caused by friction and differences in air pressure.
(a)
LIFT has to be greater than the WEIGHT (GRAVITY) in order to fly.
TRUE
FALSE
The more THRUST. The more DRAG in flight.
