2. How Humans Tried to Fly in Ancient Times
And maybe not so ancient….

3. Flight in Ancient Times
Humans have dreamed of taking flight for thousands of years
Flight is the act of passing through the air on wings
People told tales about flight around the fire at night and handed down these stories to their children

4. First True Stories of Human Attempts to Fly
Some early inventors made devices of lightweight material in imitation of birds’ or bats’ wings
As early as the 6th century AD, there has been recoded attempts to fly, generally using kites or gliding flight.

5. Armen Firman and Ibn Firnas
A Moor named Armen Firman made the first known recorded human attempt to fly in 852 AD
He put on a huge cloak and jumped from a tower in Cordoba, Spain. He hoped that it would open wide like a bat’s wings to slow him on the way down….it sort of worked.
Observing the flight was Ibn Firnas, an early flight engineer who built and flew a more advanced design in 875 AD.

6. Aviation Devices From Ancient Times

7. Chinese Advances in Flight
The Chinese invented the kite around 1000 BC
Used initially as a physiological warfare weapon by Chinese Generals
Chinese “Fire Arrows” (1045 AD)

8. Leonardo da Vinci
A visionary pioneer in so many fields, Leonardo da Vinci (1452–1519) revolutionized the concepts of aviation and mechanical design

11. Daniel Bernoulli
The Dutch-born scientist Daniel Bernoulli (1700–1782) discovered that a fluid has a constant pressure, but when a fluid starts to move faster, the pressure drops

12. Sir Isaac Newton
The Englishman Sir Isaac Newton ( ) formulated three famous laws of motion

13. Theory of Flight Newton’s Laws of Motion First Law of Motion
“A body at rest tends to remain at rest, and a body in motion tends to stay in motion, unless an outside force acts on the body.” It is sometimes referred to as the Law of Inertia.
One of the most common places people feel this law is in a fast moving vehicle. If you were standing inside a train and it suddenly stopped, you would continue to move forward even though the train had come to a stop.

14. Force = Mass x Acceleration
Theory of Flight
Newton’s Laws of Motion
Second Law of Motion
“The acceleration of an object as produced by a net force, is directly proportional to the magnitude of the net force in the same direction as the net force and inversely proportional to the mass of the object.”
Hitting a golf ball is a common example of Newton’s second law. The golf club is a force that causes the ball to move (overcoming inertia), and picks up speed (acceleration) and since the golf ball is relatively light, it picks up speed rapidly.
Force = Mass x Acceleration
F=MxA
Second Law of Motion
"The acceleration of an object as produced by a net force, is directly proportional to the magnitude of the net force in the same direction as the net force and inversely proportional to the mass of the object." Simply stated:
When you hit something, it will pick up speed.
The heavier the object is, the less rapidly it will pick up speed.
The object picks up speed and continues to move in the same direction from which it was hit.

15. Theory of Flight Newton’s Laws of Motion Third Law of Motion
“Whenever one body exerts a force upon a second body, the second exerts an equal and opposite force upon the first body.” Simply stated, For every action there is an equal and opposite reaction.”
Third Law of Motion
"Whenever one body exerts a force upon a second body, the second exerts an equal and opposite force upon the first body." Simply stated, For every action there is an equal and opposite reaction."
