Formula

a_tidal = 2GMd / r^3

Frequently Asked Questions

What is tidal force?
Tidal force is the difference in gravitational pull across an extended object. It causes tides on Earth and can tear apart bodies near massive objects.
Why does tidal force depend on r^3?
Tidal force is the gradient of gravity, which falls off as 1/r^2. The derivative gives 1/r^3 dependence.
