What Goes Up, Must Come Down

This week, we did the Ball Toss Lab.  When Coach Chris showed us an example of what we were doing in the lab, he took a volleyball and threw it up 2 meters and then caught it at the same level he threw it from.  This reminded me of when my friends and I were trying to capture a picture of us jumping together. Coach Chris taught us that when an object is thrown in the air, its velocity goes slow, fast, stop, slow, fast.  This weekend I was just looking over my pictures and I remembered when we were all jumping in the air! It made me think that when we were jumping that we started off slow, then sped up as we got to the top, and then stopped in the air, and as we came down it went slow, and then fast as we hit the floor. This Ball Toss Lab helped me realize that whenever something goes up, it must come down, but when it is in the air, it has different velocities.
