Friction Pins and Buttons
Description: A whimsical drawing featuring a smiling stick figure in an orange top. Surrounding the figure are various science concepts: a prism showing a rainbow, cherries, two graphs, a tornado, a planetary orbit with colored dots, and a block on an inclined plane labeled 'Friction' with '0$' text. The style is cartoonish and simple.
Description: A scientific diagram illustrating the progression of celestial bodies. It begins with a comet, followed by an asteroid, then a meteoroid. A meteor is depicted burning due to friction as it enters the atmosphere, and finally, a meteorite is shown impacting water.

Description: A dark background displays the word "PHYSICS" in large, colorful bubble letters at the top. Below, a blue diagram shows a block on an inclined plane with various force arrows labeled Fn, Fg, and Ff. Equations including 'N = |Fg| sin 0', 'Fg = mg sin 0', and 'Friction' are visible. To the right, the equation 'f = ΣN' is displayed in green bubble letters.
Description: A diagram illustrating forces on an object on an inclined plane. It shows vectors labeled N, f, mg, mg sin θ, and mg cos θ, representing normal force, frictional force, and gravitational force components. Text reads 'Incliend plane', 'Frictional', 'Normal perpendicular to', and 'Indiend plane'.
Description: I made a video entitled “The Anatomy of Ruffled Feathers” https://youtu.be/-ilcQ1Q3tTk?si=VpDDDqCRavxjuDTO) on my YouTube channel where you can see these actual Abert’s Towhees engage in this heated conflict. I thought this saying goes with it as well. It is an esoteric maxim: nothing moves without there first being some kind of friction.
