Flapping of a flag in wind
motion
Answers
Answer:
Since gravity tends to collapse a flag along its diagonal, while wind tends to stretch it out, the wave like motion of folds in a flag is at an oblique angle to its length
Explanation:
"From the experiment, it is quite clear that the flapping of a 'flag' is not because of the turbulence in the wind, or the presence of the flagpole," says Zhang. "It is intrinsically embedded in the system, as a result of the inertia dynamics of the flag interacting with the surrounding fluid flow
Answer:
Flapping of the Flag in wind in caused due to Periodic Motion.
Explanation:
What is Periodic Motion?
The motion which is repeated in equal interval of time is called periodic motion.
The Law of Inertia states that a object is always move in straight line unless and until any force acts on them deviate it.
The Flapping of Flag in the Wind is depended on this principle. When the wind moves in the direction of the flag, it provides a motion or inertia on it and that's how the flag is moving.
This is a concept of Aerodynamics which help in the movement of flag.
What is Aerodynamics?
It is defined as the way the objects move in the air. It work by combining three forces, thrust, lift, drag and weight.
If anyone travel through the atmosphere, the aerodynamics concept is very important. So they help in building the bases of airplanes and other objects which is travelling in the atmosphere.
