Condition :	Good
Principle :	Gravitational Acceleration vs Horizontal Velocity
Area of Study :	Mechanics
Equipment :	Stuffed monkey with target plate, Magnetic coil, Control box with air line, Air gun, Ammunition (small steel balls), Spring-loaded gun, Steel ball for gun (solid), Steel ball for gun (hole in middle), Shoot the Monkey App. from Pasco
Procedure :	The setup is pretty much self evident from the photographs, with special attention to three parts. Make sure the electronic plug from the air gun is plugged into the control box right side up. Connect the air hose to the proper end of the air gun (the end opposite the photocell). Load ammunition into the gun before pressing the reset button and positioning the monkey. The Pasco apparatus works much the same with two minor variations. The first is that this uses a spring gun and not an air gun. The second is the make up of the magnet that hold the monkey. Instead of having a continuously energized electromagnet, this uses a permanent magnet that is momentarily canceled with a electromagnet.
