Random walk with statistics - random
angle movement - up
down left or right - up
down random but always left or right on alternating rows
Continuous random walk - up down left or right - up down random, randomized rows are single direction (resulting in "super-diffusive motion)
Pendulum - elastic
collision - projectile - coupled
cycloid - variable cycloid
Speed test - how many particles can flash/action script handle?
Guess-timate: How many dots are there? -- What
is the fraction of red dots?
Mean and standard deviation in a line distribution -- What is the mean and standard deviation of a two dimensional pattern of dots?
Chain reaction - Chain reaction with variable spacing between targets
An attempt at Ohm's Law
An attempt at a diode - holes and electrons diffuse in p and n materials, a red dot shows where they combine. Each red dot increases the charge difference between the p and n sides, which hinders diffusion of holes into the n side and electrons into the p side, so that eventually a "depletion zone" develops at the boundary between the p and m sides.
