一:地心引力,重力的是什么意思(中英文)解释的意思:
地心引力是指天体之间相互吸引的力量,是由于物体之间的质量和距离而产生的。重力是指地球表面上物体受到的向下拉的力量,也可以理解为物体受到地心引力作用后产生的效果。
Gravity is the force of attraction between celestial bodies, caused by their mass and distance. It is also the downward force that objects on Earth experience, which can be understood as the effect of being affected by the force of gravity from the Earth's center.
地心引力:dì xīn yǐn lì (dì xīn yǐn lì)
三:用法:
地心引力和重力都是物理学中常用的概念,可以用来解释天体运动、物体运动等现象。在日常生活中,我们也可以用它们来描述物体受到的各种影响和作用。
1. The moon orbits around the Earth due to the force of gravity.
2. The weight of an object on Earth is determined by its mass and the strength of gravity.
一个物体在地球上所受到的重量取决于它的质量和重力的强度。
3. The force of gravity on Mars is about one-third of that on Earth.
4. The astronauts experienced weightlessness in space due to the absence of gravity.
5. The force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
两个物体之间的引力与它们的质量乘积成正比,与它们之间距离的平方成反比。
地心引力和重力都可以用来表示物体之间相互吸引的力量。在不同语境下,也可以使用其他近义词来表达这一概念,比如gravitation、attraction等。
地心引力和重力是物理学中基础概念,用来解释天体运动、物体运动等现象。它们在日常生活中也有广泛的应用,对于理解世界运行规律具有重要意义。
