non inertial frame

doc.brown · Answer

Earth is in space.

kainui · Answer

The earth is an inertial reference frame for several reasons. If it wasn't, then the world wouldn't be spinning and we'd either only ever see day or night. But the world does spin, so even though everything seems still, we're really moving. Just like when you're in a car going 60 miles per hour, you feel no breeze if it's closed and you can throw a ball and it acts just like if you threw the ball while standing outside.

Although for most calculations we treat the earth as an inertial frame, which means a non-accelerating frame of reference, it does accelerate, as rotation and as revolution around the sun. Rotational acceleration has a v^2/r dependence. Our weather is also influenced by rotation, as the Coriolis forces influence large-scale air mass movements. In the earth's elliptical orbit around the sun, it travels faster when closer and more slowly when farther, indicating translational acceleration also.

practically , earth is a non-inertial ref. frame as it has an acceleration
but this acceleration is too small so we neglect it and assume the earth to be an inettial ref. frame it has an acceleration of nearly 0.003m/s^2(i don't know the correct value but it's nearly this)
