1st Law (Law of Inertia)
Every object continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed upon it.
acceleration = 0.0 unless the objected is acted on by an unbalanced force

Forces that influence the wind
1. Pressure Gradient Force
2. Coriolis Force
3. Friction
On average Gravity nearly balances the vertical Pressure gradient(hydrostatic balance)

Coriolis Force (apparent force due to Earth’s rotation)
![Page 12: Air Motions Geology 390 WSUV Dr. Robert M MacKay](https://reader033.vdocuments.mx/reader033/viewer/2022061305/551462db550346b0158b49d6/html5/thumbnails/12.jpg)
Coriolis Force
Deflects air to right in NH& Left in SH
Is always zero at the equator
Increases with latitude
Increases with wind speed
Increases as planet rotation speed increase
