- High quality metal inertia demonstration model
This heavy duty, metal inertia demonstration model is perfect for years of student abuse and classroom use. Its base is mounted on stable rubber feet with adjustable height allowing the platform to be set from 3/4" to 1" high. The 'trigger' then slides the sheet out from under the ball, dropping it into the receptacle upon the top of the post. Can be used for demonstrations in middle school, high school, and introductory college courses.
Delivery information: The unit comes with 0.75" Ø steel ball and attached, dimpled metal plate and set upon a 6" tall post.
