Definition
落体 is a physics term for a body that falls under gravity. The standard pronunciation is luò tǐ (fourth tone on each syllable), but the input row lists pinyin 'là', which is non-standard and likely a data error. In physics contexts, 落体 refers to an object in free fall or projectile motion, often analyzed under the influence of gravity alone.
