EXPERIMENTAL STUDY AND SIMULATION OF ATTRACTIVE FORCE FORMULATION OF TWO FLOATING SPHERES
Two floating ball objects that are close together interact with each other in a certain time when the initial separation distance of the two is not greater than the diameter. This interaction is due to asymmetrical deformation in the liquid-air boundary plane due to contact with spherical objects. A...

| Summary: | Two floating ball objects that are close together interact with each other in a certain time when the initial separation distance of the two is not greater than the diameter. This interaction is due to asymmetrical deformation in the liquid-air boundary plane due to contact with spherical objects. Asymmetrical deformation of the liquid-air boundary area between the two spheres and outside the sphere results in an attractive force. This final project aims to observe this phenomenon with a macro-sized object (on a centimeter scale). The method used is an experiment with digital image processing and simulation with the analogy of two masses spring system. Then, the formulation of attractive force between two objects that interact on the surface of the water towards changes the depth of the object which is influenced by variations in the density of the object can be determined. The comparison of experimental and simulation results for attractive forces with variations in object density is obtained. |
