2. Questions / Comments

3. Warm-Up – 1/25 – 10 minutes
Utilizing your notes and past knowledge answer the following questions:
Describe how lift occurs with an airfoil.
Describe how a vortex occurs
Describe winglets and their purpose.
What are Newton’s three laws of motion?
Describe Mach.

4. Who is Daniel Bernoulli?
For Lift to occur - The pressure on top of the airfoil must be less than the pressure below.
The airfoil has no choice but to move upward.

5. Warm-Up – 1/25 – 10 minutes
Utilizing your notes and past knowledge answer the following questions:
Describe who lift occurs with an airfoil.
Describe how a vortex occurs
Describe winglets and their purpose.
What are Newton’s three laws of motion?
Describe Mach.

6. A Third Dimension
The high-pressure area on the bottom of an airfoil pushes around the tip to the low-pressure area on the top.
This action creates a rotating flow called a tip vortex

7. Warm-Up – 1/25 – 10 minutes
Utilizing your notes and past knowledge answer the following questions:
Describe who lift occurs with an airfoil.
Describe how a vortex occurs
Describe winglets and their purpose.
What are Newton’s three laws of motion?
Describe Mach.

8. A Third Dimension
Winglets can be added to the tip of an airfoil to reduce this flow.
The winglets act as a dam preventing the vortex from forming.
Winglets can be on the top or bottom of the airfoil.

9. Warm-Up – 1/25 – 10 minutes
Utilizing your notes and past knowledge answer the following questions:
Describe who lift occurs with an airfoil.
Describe how a vortex occurs
Describe winglets and their purpose.
What are Newton’s three laws of motion?
Describe Mach.

10. Newton’s Laws of Motion
Newton's three laws of motion are:
Inertia - A body at rest will remain at rest. and a body in motion will remain in motion at the same speed and direction until affected by some external force.
Nothing starts or stops without an outside force to bring about or prevent motion. Hence, the force with which a body offers resistance to change is called the force of inertia.

11. Newton’s Laws of Motion
Newton's three laws of motion are:
Acceleration - The force required to produce a change in motion of a body is directly proportional to its mass and the rate of change in its velocity.
Acceleration refers either to an increase or a decrease in velocity, although Deceleration is commonly used to indicate a decrease.

12. Newton’s Laws of Motion
Newton's three laws of motion are:
Action / Reaction - For every action there is an equal and opposite reaction.
If an interaction occurs between two bodies, equal forces in opposite directions will be imparted to each body.

13. Warm-Up – 1/25 – 10 minutes
Utilizing your notes and past knowledge answer the following questions:
Describe who lift occurs with an airfoil.
Describe how a vortex occurs
Describe winglets and their purpose.
What are Newton’s three laws of motion?
Describe Mach.

14. The Speed of Sound in Air
Austrian physicist Ernst Mach determined the mathematical value for the speed of sound
Speed of sound varies with altitude because temperature decreases with an increase in height
Chuck Yeager in the X-1 broke the speed of sound Oct 14, 1947
