Valve released some new items for the educational build of the Puzzle Maker! Here’s a rehash of some older videos about momentum and collisions using the new toys.
Bonus feature! Check out this crazy oscillator device I made with contraption cubes of different masses. It’s pretty mesmerizing. The cubes get heavier from left to right but the strength of each aerial faith plate is the same.
Here’s a quick high school physics lesson.
My oscillator reminds me of the wave pendulum in the video below because both systems show repeating patterns. The swinging billiard balls form a wave with varying frequency. My oscillator also appears to be demonstrating wave-like properties.
The billiard ball pendula are oscillating on strings of varying lengths but are pulled to the same angle. The period (time of one oscillation) of a pendulum pulled back to a small angle is
Period = 2Π√(length/strength of gravity)
So, if you increase the length of the pendulum, you increase the period. Each progressively longer pendulum takes a bit more time to make one period in the same way that each progressively lighter companion cube stays in the air a bit longer. Of course, the game’s oscillations aren’t perfect. I’ll take another look at the differences between the way the cubes are bouncing and how they should bounce to determine the exact variations between the physics of aerial faith plates in the game and similar launchers in real life.
