Abstract

Hovercraft is a vehicle that glides over a smooth surface by hovering over an air cushion. Therefore, hovercraft is also called Air-Cushion Vehicle or ACV. Hovercraft creates air vents, which are trapped under the vehicle with a curtain around the base. Air currents can make air cushion on the soil, smooth surface or water. A simple mini hovercraft that used for physics learning media on the pressure principal explains the utilization of air pressure on the mini hovercraft. The making of this mini hovercraft as a learning media is aimed to show the concept of pressure. From the results of observation and analysis of the data, it was proved that air pressure generated can produce bigger lift than the mini hovercraft weight. The air flowing out from the balloon in the bottom caused the mini hovercraft to be pushed upward.
