Find a pattern for projectiles launched at angles as you vary the launch angle between 70 degrees and 20 degrees above the horizontal.


As a result of working with the sim, be able to report back with...
1.  Something you thought you knew that was confirmed
2.  Something you did not know that you now know
3.  Something that you want to know
