| Experimental components |
Small table, sponge, weights |
| Experimental process | Refer to Figure A, place the legs of the small table facing down on the sponge; then refer to Figure B, place a weight on top of the small table; finally, refer to Figure C, flip the small table over and place the weight on top of the small table. |
| Experimental phenomena | (1) Comparing the two experiments in Figures A and B, you will find that the sponge in Figure B is pressed down deeper. This indicates that when the force area is constant, the greater the pressure, the more obvious the effect of the pressure. (2) Comparing the two experiments in Figures B and C, you will find that the sponge in Figure B is pressed down deeper. This indicates that when the force is constant, the smaller the force area, the more obvious the effect of the pressure. |
| Experimental conclusion | (1) This experiment used the "control variable method" and "transformation method." (2) The effect of pressure is not only related to the magnitude of pressure but also related to the force area. In the above experiments, the pressure applied to the sponge in Figures B and C was the same, but the force area was different, resulting in different pressure per unit area, which is the reason for the difference in the depth of the impression of the small table on the sponge. (3) In physics, the ratio of pressure to force area is called pressure intensity (or the pressure per unit area of an object is called pressure intensity). The formula is p = F/S. Therefore, using pressure intensity to represent the effect of pressure, the greater the effect of pressure, the higher the pressure intensity. Obviously, in these three different experiments, the pressure intensity of the small table on the sponge in the experiment shown in Figure B is the highest. |
