Tidal forces arise from gravity gradient: near side attracted more than far side, stretching objects. Governs Moon stability and planetary rings.

  1. 1Input primary mass, satellite mass, separation distance
  2. 2Calculate tidal force gradient
  3. 3Compare to self-gravity

ସମାଧାନ ହୋଇଥିବା ଉଦାହରଣ

ଇନପୁଟ୍
Earth-Moon system
ଫଳ
Tidal force sufficient to cause 1m ocean tides
Moon receding ~3.8 cm/year

  • Confusing tidal force with mass effect
  • Neglecting density in Roche limit

ବାରମ୍ବାର ଜିଜ୍ଞାସା

When does tidal force destroy objects?

When exceeds self-gravity: Roche limit. Depends on density, composition.
