What are the 4 forces of flight?
lift, weight, drag, thrust.
Draw a diagram of what happens when air is heated and the flying machine that uses this principle.
Teacher decides, principle is air expands when heated - molecules move faster and are less dense.

Teacher decides.
145.999 + 250.001
396
What happens to the plane if the forces of weight + drag are greater than lift + thrust. What happens if it is the opposite?
It descends. It ascends or climbs.

How is the angle of attack different in takeoff vs. landing.
Upwards during takeoff, Downwards during landing.
Draw a diagram of Bernoulli's principle for both an airplane and helicopter and explain what it does for the aircraft. Bonus - What property of air does this show
Teacher decides. Provides lift from having high pressure of air molecules to push up on the blades, wings or body of the plane. Bonus answer - air exerts pressure.
Is 0.3 greater than or less than 1/3.
Less than
