Science Buddies: "Ask an Expert"

I am doing research for my science fair project of "bombs away" Please explain me the terms launch angle, pull back angle, and trajectory. Please explain to me what effect these will have on the launch distance of the ping pong ball.

Here is a set of pages on trajectory and launch angle:

These websites come from the Bibliography section of this Science Buddies Project Idea:
