Dodge, Dip, Duck, Dive and Dodge

Back in my "younger" days, all my neighborhood buddies, my brother and I all used to play games together. The one we used to play all the time was dodgeball. We played that game in our backyard so often that our grass got all dead and brown. This older boy named Christopher who was like in highschool back then (when I was in like the sixth grade) and his two younger brothers, (they were probably like seven) used to play with us. Christopher would throw the ball so hard at his two brothers and everyone that it was pretty scary. If he had the ball, he would face his back toward the people in the middle, then swirl around and just fly it out at us. Getting beaned by that ball was so sore! Well back then, I had no idea what was going on scientifically behind the scenes, but now I do. All those balls that Christopher beaned at us were projectiles. They were objects thrown, or shot as I should say, at us and then affected by gravity (although to me they just seemed to be coming straight for me). They had a horizontal and vertical motion. Because Chris would throw it at such a seemingly high velocity, the shape of the projectile, the trajectory(?) would look like a really wide parabola. The boy in the picture isn't Chris, he's my brother. If it were Christopher in this picture, the camera probably would have been broken by now.
