## 본문내용

1. Point Mass Downfall
1.1 Objective of experiment
The object falling on the curvature is off-bending in a moment and goes the free-fall. In theory, calculate the falling point of object and review the results as compared to the measuring values.

1.2 Basic theory
1.2.1 Conservation of mechanical energy
According to the principle of conservation of mechanical energy, the mechanical energy of an isolated system remains constant in time, as long as the system is free of friction and other non-conservative forces. In other words, if there are no nonconservative forces, then no nonconservative work is done and mechanical energy is conserved.
