重力（じゅうりょく、juuryoku）
- gravity

The Japanese word 重力, pronounced じゅうりょく (jūryoku), means "gravity." It refers to the force that attracts objects with mass towards each other. This is the force that causes objects to fall to the ground and keeps planets orbiting the sun. It's a fundamental force of nature.

⚫︎ 重力はリンゴを木から落とした。 Translation: Gravity made the apple fall from the tree. ⚫︎ 月の重力は地球より弱い。 Translation: The gravity on the moon is weaker than on Earth. ⚫︎ 宇宙飛行士は無重力の状態を体験した。 Translation: Astronauts experienced a state of weightlessness (literally: no gravity).

You can use 重力 in various contexts when discussing physics, space, or anything related to the force of gravity. It is used in both formal and informal conversations. For instance, when explaining how objects fall, or when discussing the effect of gravity on space exploration. You can use this word with most people, it's not very specific in formality, but it may be better to use other words when talking to small children.

重力 is typically written in kanji as 重力. The reading is じゅうりょく in hiragana. There are no other common ways to write this word. The okurigana is fixed.

There are no direct synonyms in Japanese that mean the exact same thing as "gravity". However, you can sometimes use related terms when discussing the effects or characteristics of gravity, such as: ⚫︎ 引力 (いんりょく) - attraction, gravitational force (more technical term).

There is no direct antonym for 重力. However, the concept of "weightlessness" or "absence of gravity" can be considered an antonym in terms of its effect: ⚫︎ 無重力 (むじゅうりょく) - weightlessness, zero gravity

地球の《重力は、私たちを地上に留めておく。》 ・Translation: The Earth's gravity keeps us on the ground. ・Explanation: This sentence explains how gravity affects our daily lives.

宇宙船は《重力の影響から逃れるために、高い高度まで上昇した。》 ・Translation: The spacecraft ascended to a high altitude to escape the effects of gravity. ・Explanation: This sentence discusses how a spacecraft has to deal with gravity.

The word 重力 is a compound word: ⚫︎ 重 (じゅう) - meaning "heavy" or "weight" ⚫︎ 力 (りょく) - meaning "force" or "power" Therefore, 重力 literally means "heavy force" or "force of weight," describing the gravitational force.
