Formula
ฤ = (21/2) ร (Rโตnโตeยฒ) / (Gฮผ) ร (MยฒGยฒ/aโถ)
Tidal dissipation heats moons orbiting massive planets. Io is the best example, heated by Jupiter's tidal forces due to its eccentric orbit.
Worked Examples
Example 1: Io
Problem:R=1821km, e=0.0041, P=1.77 days
Solution:Tidal heating โ 10ยนโด W (~100 TW)
Result:~100 TW
Frequently Asked Questions
How do tides work and what causes tidal patterns?
Tides are caused by gravitational pull of the moon (primary) and sun on Earth's oceans. Most coastlines experience two high and two low tides per day (semidiurnal). Spring tides (highest range) occur during full and new moons when sun and moon align. Neap tides (lowest range) occur during quarter moons.
