1D60.56 - Parabolic Trajectory - Block and Tables

Code Number:
Demo Title:
Parabolic Trajectory - Block and Tables
Parabolic Trajectory
Area of Study:
Two tables and some blocks.

Start with the tables 1 foot apart.  Place the small block at the edge of one table and hit it with the big block so that it tries to jump the gap.  As long as the gap between tables is larger than the small block, the block will always experience some fall due to gravity and therefore not land on the second table, but fall into the gap after striking the edge of the second table.
