传送带上物体的运动主要由于摩擦力引起,涉及运动、相对运动和功能转化等问题,属于典型的动力学问题.实际的传送带可能水平放置,也可以倾斜放置,相比之下,倾斜传送带更加复杂.传送带可以顺时针转动,也可以逆时针转动;物块可以放在顶端,也可以放在底端;摩擦力可以是静摩擦力,也可以是滑动摩擦力,还可能发生突变.但无论如何变化,万变不离其 Conveyor belt object movement mainly due to friction caused by movement, relative movement and function conversion and other issues, is a typical dynamic problem. Actual conveyor may be placed horizontally, you can also tilt placed, in contrast, inclined conveyor belt more complex The belt can be rotated either clockwise or counterclockwise; the mass can be placed on the top or on the bottom; the friction can be either static or sliding friction, but it can also mutate but in any case change , Unchanged
