Today i have learnt about aerodynamics here is the video :
Aero means air , While dynamic means moving. Aerodynamic means moving in air using air is known as aerodynamics .There are 3 steps to create a module , Crafting , Designing and testing. There are 3 forces that act on a plane. They are Thrust,Lift , Drag, Weight.
Lift - A force that makes the plane fly.
Drag - A force that that slows down the plane.
Weight - A force that pulls the plane down.
Thrust : A forces that make a plane move forward.
Definition about the video :
Objective to make the balloon go inside the Bottle with out pushing it. For this to work we need to learn about a principle called bernali's principle . Where the air which is in a high pressure area always move to low pressure area . So what i am going to do now is i am gonna put a burning paper inside and immediately put the water balloon on top as you can see it goes in , But how? You see that burning of paper needs o2 so after closing the bottle with the balloon the paper will take every o2 and eventually stop burning . Because of that the area inside the can will have low pressure as bernaulis principle high pressure air will go to low pressure . So what will happen here is the high pressure air will rush to get inside of the can , But the water balloon we kept will block the air for a certain time after that the balloon will go inside . So this how i made the balloon inside without touching it.
