This is a picture of my friend Courtney and I taking pictures of ourselves as seen on tv!!! ok yea so its a camera hooked up to the Tv but its still pretty cool. The tv is connected to the power outlet in the wall with has a voltage of either 120 V or 0V at any moment. The current flows through the complete circuit starting from the 120 V outlet to the tv where the charge is used and the V is returned to zero until the new electrons from the outlet are supplied. Because the outlet is 120 the charge of the electrons will be 120. The tv also has some resistance so that the real charge used will not be the full 120. THe more resistant the circuit the smaller the current. YAY we are on tv :0

This is Angelica and me sitting on a floaty raft in the pool. We were being stupid and trying to push ourselves across the pool with just our legs while balancing on it. As we push against the water with our legs, the water pushes back, propelling us forward. We must keep the mass and distance from the center of each person equal so that we won't tip over. I am assuming that we will learn why the reflection of the water is blue and other aspects of this picture soon!!

This is a picture of Laurel, Courtney, and I messing around at our friend's seventeenth bday party. We are all in different positions and balancing on one foot. This requires our center of gravity to be directly underneath us because if it is outside of the area below us, we would fall over. The more unequally distributed your mass is, the easier it is balance. Therefore the move that courtney is doing moves her CM further away from her leg on the ground. Also, we push against the ground as the ground pushes us back. This is the law of equal and opposite force. If you are actually doing these positions you would realize that you must continually push and grip your toes onto the ground.
