Tidal forces arise from gravity gradient: near side attracted more than far side, stretching objects. Governs Moon stability and planetary rings.
Guida passo passo
- 1Input primary mass, satellite mass, separation distance
- 2Calculate tidal force gradient
- 3Compare to self-gravity
Esempi risolti
Ingresso
Earth-Moon system
Risultato
Tidal force sufficient to cause 1m ocean tides
Moon receding ~3.8 cm/year
Errori comuni da evitare
- ✕Confusing tidal force with mass effect
- ✕Neglecting density in Roche limit
Domande frequenti
When does tidal force destroy objects?
When exceeds self-gravity: Roche limit. Depends on density, composition.
