Product Information
Demonstrate the relationship between acceleration, mass, and center of gravity.
This set includes two acceleration planes: one with two tracks of equal width (19 mm) and the other plane with three tracks, all of different widths (19 mm, 25 mm, and 37 mm).
When two different-sized marbles are used on the equal-sized tracks, they will accelerate at different rates. But when the three different-sized marbles with radii each as wide as their respective tracks are released simultaneously, they will all accelerate at the same rate.
Both planes are 121 x 15 cm, are made of varnished hardwood.
Comes complete with five steel marbles (one 19 mm dia., one 37 mm dia., and three 25 mm dia.) and
instructions. Developed by Bruce Yeany. Grades 7-12.
