This research aimed at analyzing the difficulties experienced by college students in acquiring Static Fluid concept. This research employed descriptive quantitative procedure and involved 48 college students of Physics Education Department. The instrument of this research was 13 items of reasoned-multiple choices test. According to the results, although there was an improvement, most college students were difficult to understand certain concepts. This research revelaed some difficulties experienced by students on certain concept. The difficulties experienced by students are as follows: students failed to portray the forces that worked on certain object and as a result, they failed to determine the ratio of pressure. In addition, the students were difficult to determine the changing of water pressure on the closed vessel based on major concept of hydrostatics and Pascal’s Law.
