The utility model discloses a ramp-adjustable teaching aid for physical experiments, which comprises an inclined plate and a bottom plate. One end of the inclined plate is hinged to the bottom plate. Positioning columns are arranged on both sides of one end of the inclined plate, wherein the end of the inclined plate is far away from a hinged shaft. The two side edges of the bottom plate are respectively provided with an arc-shaped plate. The arc-shaped plates are provided with limiting holes. The limiting holes are in coincidence with the rotation tracks of the positioning columns around the hinged shaft. The positioning columns are provided with locking nuts. According to the technical scheme of the utility model, the ramp-adjustable teaching aid is simple in structure and reasonable in design. Due to the unique design of the positioning columns and the limiting holes, the inclined plate can be freely adjusted within an angle range of 0-90 degrees. Then the positioning columns are locked by the locking nuts
