2 cards from this section. Quick, good the night before a test.
What is drag?
Think about what happens when you try to move through water.
Define lift.
What helps airplanes rise into the air?
What is the primary force opposing motion in fluid mechanics?
It's the opposite of thrust.
True or False: Lift acts parallel to the direction of motion.
Think about how wings work.
A rectangular box with a width of 1 m, length of 0.5 m, and height of 0.8 m is moving through air at 10 m/s. Calculate the drag force if the drag coefficient is 2. Airstream density is 1.225 kg/m³.
Remember to calculate the area correctly based on the dimensions given.
Discuss how altering the angle of attack of an airplane wing can affect lift and drag during flight.
Think of how the airflow changes around the wing.
