Club Season YAY!

These are my 2011-2012 Jammers 17 girls! This past weekend, we had our first practice with our new coach, Coach Daryl Kapis. There are multiple examples of physics during a single volleyball practice. In class, we learned that work is any change in energy or force x displacement. Simply grabbing a ball from the cart is work. We also learned that the energy of a position is potential energy. Gravitational potential energy is mass x gravity x height. For example, holding a volleyball before serving for myself would have the potential energy of 0.27 kg (weight of volleyball) x 9.8 m/s2 (gravity of earth) x 1.22 meters (height of ball). The volleyball would have an approximate gravitational potential energy of 3.23 Joules.
