These days were spent preparing and completing the Culminating Lab. The lab involved observing the relationship between velocity and height in a pendulum while at the same time, verifying the Law of Conservation of Mechanical Energy.
In case it’s been forgotten (a previous post was made about this law), the Law of Conservation of Mechanical Energy states that no energy is lost and no energy appears out of nowhere. Essentially, the energy will remain constant in a system unless energy is taken out of a system and moved somewhere else. In the case of the pendulum, it was determined that the energy should theoretically be conserved (potential energy converting to kinetic (movement) and then back to original potential energy) however, some energy was removed by the system by air resistance.
