INTERCAMBIO DE ENERGÍA EN EL IMPACTO DE UNA ESFERA CON LA SUPERFICIE DE UN LÍQUIDO.

In the course of General Physics it is possible to find the problem related to the study of the motion of bodies in a liquid when their densities are greater than that of the liquid. A problem not found in the bibliography consulted is: What depth will be obtained for an sphere when it falls freely from a height H above the free surface, if its density is less than that of the liquid? To carry out the study of this problem, a theoretical model was applied and an analytical solution was found to this depth. In addition, an experiment was designed based in the video analysis technique, using Tracker for Windows to know the real depth obtained. The main goal of this paper is to estimate the energy interchanged in the impact of the sphere on the surface linking both results. [ABSTRACT FROM AUTHOR]
