Title: Agua Loco
Student: Jayme Lauren Littlefield
School: Apponequet Regional High School, Lakeville, Massachusetts
Teacher: Julie Mills

The unique ?stream? of water seen in the photograph demonstrates Isaac Newton?s First Law of Motion. His law states that a body persists its state of rest or of uniform motion unless acted upon by an external unbalanced force. Due to gravity, as the water exits the faucet its tendency is to head directly down, or towards the sink. As the ?source? of the water is quickly moved, the water already expelled from the faucet continues its straight, downward path. The water near the faucet, is being acted on by both gravity and a sideways applied force from the person?s hand. For a split second, the stream of water appears to be flowing sideways, while in actuality, it is simply falling toward the Earth at -9.8 m/s2. The stream of water remains unbroken due to the cohesive property of water. Water molecules are partially polar so they will tend to attract each other because of the electrical attraction between opposite charges. This phenomena cannot be fully appreciated with the naked eye, yet a still photograph shows the wonder of water, inertia, cohesion and gravity.
