Learning Objective
I can analyze the forces that enable and affect flight.
- 1
The four forces of flight are lift, weight, drag, and thrust.
- 2
Bernoulli's principle states that faster moving air has a lower air pressure, and slower moving air exerts a higher pressure, which helps generate lift.
- 3
Earth's gravity affects everything at the same rate of 9.81 meters per second squared, but drag can change the rate at which objects fall.
