This is a simulation that shows a ball traveling to areas with different amounts of friction. First, you will be asked the angle and initial velocity of the ball. After that, click on a square of the grid to change the amount of friction on that square. Colors will show the amount of friction. All squares start as white. When clicked, they change to yellow, red, green, and back to white. White: medium friction Yellow: high friction Red: very high friction Green: low friction
This Scratch wiki article helped me keep individual colors and locations for each square: https://wiki.scratch.mit.edu/wiki/Advanced_Clone_Usage
