在某些与摩擦有关的物理现象里.摩擦这个因素有时是隐含着的.如果在解释这些现象时.忽视了摩擦这个隐含因素.就会造成错误.例1 用力推放在地面上的衣箱.为什么有时推不动?错解推而不动是因为推力太小而木箱保持静止状态的惯性又较大。
In some friction-related physical phenomena, the friction factor is sometimes implied. If these phenomena are explained, the implied factor of friction is ignored. This causes an error. Example 1 Push hard on the ground The trunk. Why is it sometimes impossible to push it? The wrong solution is pushed because the thrust is too small and the inertia of the wooden box remains static.
