Large Inertia Demonstration Model

This large inertia demonstration model features a heavy-duty metal construction with a 6.5 x 6.5 inch base mounted on stable rubber feet with adjustable height from 3/4 inch to 1 inch. The unit includes a 0.75-inch diameter steel ball placed on a dimpled metal plate atop a 6-inch tall post. The trigger mechanism slides the plate from under the ball, dropping it into the receptacle on top of the post. Total dimensions: 6.5 x 6.5 x 8 inches. Provides a clear demonstration of Newton's first law of motion. Suitable as a teaching tool for middle school through introductory college physics courses.
