重力勢能的意思、翻譯和例句

是什麼意思

「重力勢能」是指物體因其位置而具有的潛在能量,特別是由於地球的引力作用而產生的能量。當一個物體在地球的重力場中被提升到一定高度時,它便儲存了重力勢能。這種能量可以在物體下落時轉化為動能。重力勢能的計算公式為: 重力勢能 = mgh 其中,m 是物體的質量,g 是重力加速度(約為9.81 m/s²),h 是物體的高度。

  1. Energy stored due to height.
  2. Energy related to how high something is.
  3. Energy that depends on an object's position.
  4. Energy that an object has because of its height above the ground.
  5. The energy an object possesses due to its position in a gravitational field.
  6. Potential energy that is dependent on the height of an object in a gravitational field.
  7. The stored energy in an object resulting from its elevation in a gravitational field.
  8. The energy associated with the position of an object relative to a gravitational source.
  9. A form of potential energy that is determined by the gravitational force acting on an object's mass and its height.
  10. The energy an object has due to its position in a gravitational field, often related to its height above a reference point.

1:Gravitational potential energy

用法:

這是一個物理學術語,專門用來描述由於重力作用而儲存的能量。當物體在重力場中位置改變時,這種能量會隨之改變。通常用於解釋物體在自由落體運動或上升運動中的能量轉換。

例句 1:

當這個球被抬高時,它的重力勢能增加。

As the ball is lifted, its gravitational potential energy increases.

例句 2:

在山頂,滑雪者的重力勢能達到最大值。

At the top of the mountain, the skier's gravitational potential energy reaches its maximum.

例句 3:

重力勢能的變化可以用公式進行計算。

2:Potential energy

用法:

這是一個更廣泛的術語,涵蓋了多種形式的潛在能量,包括重力勢能、彈性勢能等。它指的是物體因其位置或狀態而儲存的能量,這些能量可以在適當的情況下轉化為其他形式的能量。

3:Height energy

用法:

這是一個不太常用的術語,專門指與高度相關的能量,通常與重力勢能相同。它強調了物體因其高度而儲存的能量。

例句及翻譯:

這個物體的高度能量隨著它的高度增加而增加。

The height energy of this object increases as its height increases.

例句 2:

在這個實驗中,我們測量了不同高度的高度能量。

In this experiment, we measured the height energy at different elevations.
