What is the apparent curving of the path of a moving object from an otherwise straight path due to earths rotation?

Answer 1

This happens because earth is not a perfectly inertial frame of reference (it rotates). In rotating frames of reference the coriolis force makes the paths curve.

There is some dissent about the coriolis force. Its a little like calling the force that moves you to one side in a turning car centrifugal force - actually, it is a centripetal reaction force from the door pushing on you, rather than the other way around, because you are tending to travel in a straight line. For the same reason, coriolis force (more correctly, coriolis effect) is due to objects wanting to travel in straight lines underneath a moving earth.

Answer 2

Air naturally moves from areas of high pressure to areas of low pressure, due to the pressure gradient force. As soon as the air starts to move, however, the Coriolis force deflects it due to the rotation of the earth. The deflection is to the right in the northern hemisphere, and to the left in the Southern Hemisphere. As the air moves from the high pressure area, its speed increases, and so does the deflection from the Coriolis force. The deflection increases until the Coriolis and pressure gradient forces are in geostrophic balance, at which point the air is no longer moving from high to low pressure, but instead moves along an isobar, a line of equal pressure.

Answer 3

What's the effect that causes objects to move in a curved direction do to the arse rotation

Answer 4

Coriolis effect!

Answer 5

Coriolis force

Answer 6

The curving of a path of a moving object from an otherwise straight path due to Earth's rotation winds that blow from east to west between 60 and 90 degrees latitude in both hemispheres narrow belts of strong winds that blow in the upper troposphere
