我们知道,滑动摩擦力的大小跟压力成正比,还跟接触面的性质有关,采用图1来完成关于滑动摩擦力大小与物体间压力关系实验探究。将质量为m的木块放在固定的有粗糙表面的水平木板上,用力F拉木块,使木块沿水平方向匀速滑动(图1),记录拉力F的值。通过在木块上加砝码改变压力N,同时改变拉力F,仍使木块沿水平面匀速滑动,记录各次的N、F值,研究N与F的关系。 We know that the size of sliding friction is proportional to the pressure, but also with the nature of the contact surface, the use of Figure 1 to complete the sliding friction between the size and pressure on the relationship between the object to explore. Place a block of wood of mass m on a fixed plank with a rough surface, pull the block with force, and slide the block horizontally (Figure 1). By changing the pressure N on the block and changing the tension F at the same time, the block still slides along the horizontal plane at a constant speed. The values ​​of N and F are recorded and the relationship between N and F is studied.
