Image of six colored balls used to illustrate the effectiveness of the searching algorithm. From left to right they are yellow, black, red, orange, blue, and green.
Original image processed to search for the yellow ball with RGB values of 255, 190, and 0, respectively. In these examples, .
The original image is processed to search for the red ball using RGB values of 170, 10, and 30, respectively.
Plot of the figure of merit (FOM) for various RGB color combinations near the color of the red and orange balls. The algorithm uses the original image in Fig. 1 and .
Sample image of yellow croquette ball pendulum. The fishing line string holding the ball (not readily visible) is approximately long.
Plot of the and position of the yellow pendulum as a function of time.
Detected laser spot used in the Cavendish experiment.
Geometry of the two-dimensional collision with rolling balls. The dashed lines represent the rolling axis as the ball moves. The solid ball is initially stationary.
Computer observed position of the projectile (ball 1) and the target (ball 2) at various times. The plotted and errors are based on Eq. (4), which can overestimate the uncertainty.
Projectile (ball 1) position as a function of time. Based on a linear regression, the ball’s initial velocity in the direction is .
Ball 1 position as a function of time. The slope gives a velocity of .
