This book contains graphs showing the motion of marbles as they travel on a variety of inclined surfaces, including flat wood and curved metal inclines. Paths are complex, with an initial incline followed by a flat surface, drop, ramp, or wall. Comparison graphs include free fall and bouncing on carpet. The experiments focus on four marbles, plus a rubber ball for comparison. These data can be used for lesson plans by teachers and parents.
