Conservation of Energy Melissa Stumbaugh Andrew Raymond
... Figure 1 depicts the results from the air track portion of the lab. The graph shows that as the potential energy decreases, the kinetic energy increases. This trade off supports the principle of conservation of energy. When the total energy was plotted against position, a relatively straight across ...
