動摩擦力的意思、翻譯和例句

是什麼意思

「動摩擦力」是指物體在運動過程中,與接觸面之間產生的摩擦力。這種摩擦力的大小通常取決於物體的質量、運動速度以及接觸面的性質。動摩擦力的方向與物體的運動方向相反,並且通常小於靜摩擦力。

  1. The force that resists motion between two surfaces that are sliding past each other.
  2. The force that slows down moving objects when they touch another surface.
  3. The force that acts against the motion of an object in contact with another surface.
  4. The force that opposes the movement of two surfaces sliding against each other.
  5. The force that arises when two surfaces are in motion relative to each other.
  6. The frictional force that occurs when an object slides over a surface.
  7. The resistance encountered by an object in motion due to contact with another surface.
  8. The force that opposes the relative motion of solid surfaces in contact.
  9. The kinetic force that acts to impede the sliding motion of an object against a surface.
  10. The force that counteracts the sliding motion of one surface over another.

1:Kinetic friction

用法:

這是一種描述物體在運動過程中與接觸面之間的摩擦力。它是動摩擦力的另一種表達方式,通常在物理學中使用。這種摩擦力的大小和性質取決於物體的運動狀態和接觸材料的特性。

例句及翻譯:

例句 1:

當物體在地面上滑動時,會產生動摩擦力

When an object slides on the ground, kinetic friction is produced.

例句 2:

這個實驗測試了不同表面之間的動摩擦力

例句 3:

動摩擦力的大小與物體的速度有關。

The magnitude of kinetic friction is related to the speed of the object.

2:Sliding friction

用法:

這個術語指的是物體在滑動過程中與接觸面之間的摩擦力。它通常用來描述物體在一個平面上滑動時所遇到的阻力。這種摩擦力在物理學和工程學中是非常重要的,因為它影響到運動的效率和穩定性。
