反作用力 (fǎn zuō) — reaction force (physics)

Definition

Examples

• 根据牛顿第三定律，每一个作用力都有一个相等的反作用力。
  Gēn jù niú dùn dì sān dìng lǜ, měi yí gè zuò yòng lì dōu yǒu yí gè xiāng děng de fǎn zuō.
  According to Newton's third law, every action force has an equal reaction force.
• 火箭飞行靠的是燃料燃烧产生的反作用力。
  Huǒ jiàn fēi xíng kào de shì rán liào rán shāo chǎn shēng de fǎn zuō.
  Rocket flight relies on the reaction force produced by fuel combustion.
• 走路时，脚给地面一个向后的力，地面就给脚一个向前的反作用力。
  Zǒu lù shí, jiǎo gěi dì miàn yí gè xiàng hòu de lì, dì miàn jiù gěi jiǎo yí gè xiàng qián de fǎn zuō.
  When walking, your foot exerts a backward force on the ground, and the ground gives your foot a forward reaction force.
