A swing and a Ferris wheel
Since I realized that I became a lioness I have spent almost my time to do reconstruction of my theory. Whereas, I often play in the field inside of the fence. There is only a swing that made by wood, which is the only play equipment I have here.
As you might not know that a swing is something special for a physicist.
I mean, if I rock the swing back and forth, I can know an equation of motion for a simple pendulum on it. If I horizontally turn the swing, I can know an equation of motion for rotation on it. Also, feeling acceleration and zero gravity, and realizing that kinetic energy is zero, are good ways for me to be relaxed.
Just in case, I would like to tell you that every physicist is not always attracted by a swing like I am.
I am able to look over view over the fence. If I do not like my situation, I would like to escape from here. Whereas, I totally like my situation now as being a lioness of physicist.
If it is feasible, I want to see whole a Ferris wheel that is in from to my fence. Because the fence hides a part of the Ferris wheel.
Oh, I guess you would like to ask me the reason.
The reason is very simple; because a Ferris wheel is something special a physicist, especially for me.
It indeed enables me to calculate equations of motion and rotation on it, and free-fall motion from it, having or not having the existence of air resistance and the effect from the rotation of the earth, and so on.
Just in case, I would like to tell you that every physicist is not always attracted by a Ferris wheel like I am.
