## Tidal Force
Tidal forces arise because gravity varies with distance. The near side of an object feels a stronger pull than the far side.
### Formula
**a_tidal = 2 G M dr / d cubed**
- *M* = mass of the tidal source
- *d* = distance from the source
- *dr* = size of the object being tidally stretched
This is the leading term in a Taylor expansion of the gravitational field.

हल किया गया उदाहरण
Moon's tidal pull across Earth (M = 7.342e22 kg, d = 3.844e8 m, dr = 1.274e7 m).
- a = 2 G M dr / d cubed
- G M = 6.674e-11 * 7.342e22 = 4.899e12
- d cubed = (3.844e8)^3 = 5.68e25
- a = 2 * 4.899e12 * 1.274e7 / 5.68e25
- a = 2.20e-6 m/s2
