[NOTE an update to the physics that is coded in...the acceleration of the turtles' slowing down on the beach is independent of their mass now, before it was inversely proportional]
A project to help learn what makes it hard for a moving object to stop.
Three turtles slide onto the beach and stop.
Challenge: Play with different settings of mass and velocity to see if you can get them to stop at the same distance as each other!
(optional try to stop on the line between the sand and the grass)
Note: There are graphs you can choose to Show/Hide.
