This unit has been stressful so far. It has been somewhat confusing, to my dismay, but I am pushing through it and learning a lot. This picture of me on this sled in Europe clearly explains this unit so far because in this case I have become the projectile. As I go down the gleaming white snowy hill I am being affected solely by gravity. Nothing else is causing me to move faster or slower down the hill; except air resistance, maybe. In order to find out how far I went we would need to first calculate the time it took for me to go down the hill and then we could calculate my distance that I traveled. Because you must have the time before you can find the distance.
