Physics of sports video

This is my physics of sport video I don't really know what we did to make this video i was gone for the making of this video and wasn't able to do much but I was here for the beginning of the process  Kailee took the corner kick and we put the video in slow motion and after she took the corner kick she headed the ball  into the goal and thats all i know of what we did.

I didn't do anything exept recording and I wasnt there so I didn't help but I could have helped more while I was away
