考测点导航压强是初中物理中重点知识,属理解层次。理解垂直作用在物体表面上的力叫做压力。它是由于物体受到挤压而产生的。课本中先做实验,在实验中运用了条件控制法的研究方法得出了压力作用的效果,不仅与压力大小有关,还与受压面积大小有关的结论,继而上升为理论——压强。压强公式p=F/S,压强的单位:Pa。压强知识的
The navigation pressure at the test site is the key knowledge in junior high school physics and it is an understanding level. Understanding the force acting perpendicular to the surface of the object is called pressure. It is due to the object being squeezed. In the textbook, the experiment was first performed. In the experiment, the method of condition control was used to obtain the effect of pressure. It was not only related to the size of the pressure, but also related to the size of the area under pressure, and then rose to the theory-pressure. Pressure formula p = F / S, pressure unit: Pa. Pressure knowledge
