사용 가이드

맥락: science, education

어조: neutral

올바른 표현

• 物体所受的浮力等于其排开液体的重力。(The buoyancy force on an object equals the weight of the fluid it displaces.)
• 船只能够漂浮在水面上，是因为所受浮力大于自身重力。(A ship floats because the buoyancy it receives exceeds its own weight.)

피해야 할 표현

• 空气中也没有浮力 — air does provide buoyancy; use 空气浮力 if referring specifically to the buoyancy in air
