Lesson 9 Understanding Goals
Subject Matter
- The pressure in a fluid decreases as the speed of the fluid increases in a steady flow.
- Lift is possible because air has to travel further over curved surfaces than straight surfaces.
Causality
- A relational causal model can be used to understand lift and Bernoulli's Principle.
