As the whirligig is released, the force of gravity pulls the toy downward but without spinning. The air beneath hits the wings and pushes them upward. The other two opposing forces that push each wing towards its fold cause the toy to spin, and is called a twisting force or torque.

How does a whirligig work?
A whirligig works by using force (usually wind, but sometimes friction, a motor or a hand) to propel itself into a whirling motion. Folksy whirligigs are a moving art form in and of themselves; they use their own blades to tell a story. That's one of the things that make whirligigs so cool: their function is a part of their beauty.
Why does gravity pull us toward the ground?
In 1915, Albert Einstein figured out the answer when he published his theory of general relativity. The reason gravity pulls you toward the ground is that all objects with mass, like our Earth, actually bend and curve the fabric of the universe, called spacetime. That curvature is what you feel as gravity. What is spacetime?
Does gravity pull down on an elephant or a mouse?
Gravity is an acceleration g that pulls down the same on an elephant or a mouse: F=g mouse and F=g Elephant. The force is different but the gravity (acceleration) is the acceleration is the same. Q: Does gravity pull down more on an elephant or on mouse?
What is gravity and how does it work?
Remember, gravity is the idea that objects in the universe are attracted to each other because spacetime is bent and curved. When Einstein came up with general relativity, he showed that all stuff in the universe can curve spacetime – in physics terms that stuff is mass and energy.
What role does gravity play in the motion of the whirligig?
gravitational force between the whirligig and Earth, we also increase how big the air resistance can get. This allows the whirligig more time to speed up before it reaches its maximum value and results in the whirligig falling more quickly to the ground than when it has a smaller mass.
What forces act on a whirligig?
The whirligig has three forces acting upon it: air resistance and lift are pushing up while the gravitational force pulls the whirligig down. The flat piece of paper has two forces acting on it, air resistance pushing up and the gravitational force pulling down.
How do you slow down a whirligig?
Adding paper clips to the whirligig results in the whirligig falling more quickly (less time). resulting in the object falling more slowly (more time).
How does a whirligig work?

Why is it called a whirligig?
The word whirligig comes to us from Middle English whirlegigg ("whirling top"), which is itself from whirlen, meaning "to whirl," and gigg, meaning "(toy) top."

What type of art is a whirligig?
The Artist Simpson's monumental, fanciful, wind-driven creations-popularly called “whirligigs” – have been appreciated by millions of people in art museums and other venues. In 2013 they were named North Carolina's official folk art. Simpson's fame came near the end of his life.
How does a wind spinner work?
Wind spinners harness wind power to create "moving" art that's often colorful, whimsical, and three-dimensional. Many wind spinners feature two or more concentric rings that rotate on the same central axis, creating an especially remarkable "spin".

harpistBrent agrees to this, as he feels guilty for his actions. He receives a bus pass and supplies to help him build his whirligigs. When Brent arrives at Bellevue, Washington he starts to make his first whirligig, a harpist. There, he meets a cyclist who plays Go, who teaches him about the movement of life.
Is there a whirligig movie?
Whirligig was released in 2011 on Friday, May 6, 2011 (Limited release). There were 15 other movies released on the same date, including Something Borrowed, Thor and Jumping the Broom.
What happens when you release a whirligig?
After releasing the whirligig, there is something pulling it down. You know this is gravity. However, there is also something pushingup against it.Youcannot see what this “something” is. It is not your hand. Your hand is no longer touching the whirligig. What is happening is that the blades of the whirligig are falling through the air and bumping into air molecules along the way. These collisions create a push against the bottom side of the blades. Air provides a push on the whirligig that is opposite to the pull of gravity. This opposing push is called air resistance or drag.
Why does my whirligig fall?
You probably know why your whirligig falls toward the ground. It is because of gravity – the same force that you had to consider in the Book-Support Challenge. Just as Earth pulled the book toward it, Earth also pulls the whirligig toward it.
Why does gravity pull you toward the ground?
The reason gravity pulls you toward the ground is that all objects with mass, like our Earth, actually bend and curve the fabric of the universe, called spacetime. That curvature is what you feel as gravity.
Why do things with mass or energy gravitate toward each other?
Gravity is the reason things with mass or energy are attracted to each other. It is why apples fall toward the ground and planets orbit stars.

What would happen if someone went under the trampoline?
Imagine someone went under the trampoline and pushed up. The ball would roll away! This would be a gravity hill, not a gravity well. As far as scientists know, matter – or stuff – always makes gravity wells and not gravity hills. Scientists can imagine things made of exotic matter or energy that would cause gravity to push you off into space, but so far, no one has found anything that could cause gravity to push you away from Earth.
