By alternately sending the 45mm-diameter plastic and 25mm chrome steel and plastic balls down the 3.5m-long looped aluminum track, you can demonstrate how the transformation of energy doesnÍt depend on mass. You can also discuss circular motion with your class, explaining why the ball doesnÍt fall off the track at the top of the loop. And by holding the track at various angles, you can perform experiments in projectile motion. This fun and versatile apparatus will be a valued teaching aid in your classroom for years to come. Complete instructions are included. Note: This equipment must be shipped motor freight. Size: 1.7x1.1m. Shipping weight: 12lbs
