Mad Science wants to see your #amazingpaperplanes !
Aerodynamics is a term used to describe how easily or difficult something can move through the air. For your planes to be aerodynamic, you must consider 4 factors: Gravity, thrust, lift and drag.
Gravity is going to be pulling your plane towards the ground. In opposition, lift happens when the air below the planes wings is pushing up harder than it is pushing down. To help with this, paper planes are lightweight, so the air can easily keep it a float.
Put your hands out away from your body, palms down, and spin in a circle. Can you feel your arms slicing through the air?
What if you angle your hand so that it is perpendicular to the floor?
That extra push you are feeling on your palm is drag. Drag pushes against the airplane when there is too much surface area. To make our planes cut through the air, they should be sleek to catch the least amount of drag.
Finally, thrust is the power to make the plane take off: YOU! Since the plane is so lightweight, you don't have to use a lot of thrust to get it into the air. Heavier objects, like jets, need the engines to propel them, but for us the lighter throw will make your plane fly farther!
Even if your plane doesn't fly, we want to see it! The fact that you tried pays a fantastic homage to #nationalpaperairplaneday.
Have fun! #kidscience
