Without looking it up, I'll go out on a limb here and state my guess. (Then somebody else can come along and show that my guess was all wet.)

I think angular velocity and acceleration are both right-hand-rule guys, with vectors formed by (R) cross (rotation direction). If true, and rotation is from west to east (counterclock viewed from above the north pole), then the angular velocity vector points into the south pole and out of the north pole.

Correction:

You have stated the true method for the answer above, but got the opposite answer. Since the earth rotates in a counter-clockwise direction viewed from the north pole, the angular velocity vector would point from the center of the earth to the north pole. It's magnitude would be the angular velocity of the earth's spin.

-J

I think that's exactly what I said ... " ... out of the north pole".

Ah I see, my apologies. I think where I was confused was where you stated "into the south pole..." Instead you can state that it would originate from the center and point towards the north pole. You can rewrite it and delete our discussion :)

How many types of earth rotation?

It is anticlockwise when viewed from the north. This applies to both its daily rotation and its revolution around the Sun. The angular momentum vector in both cases points to the north.


How are baselines used to locate points on earths surface?

The Equator


What did Galileo use as points of reference when tracking the rotation of the sun?

sun spots


If an object is speeding up to the right what direction does its velocity vector point?

From the information given, we don't really know. We know that the acceleration vector points to the right, but the velocity could be anywhere.


What is the angular velocity of the earth around the sun?

There are two ways of describing this movement, both assuming that the North Pole is at the "top" of the Earth, which is how the world is normally shown. It can be said that the Earth turns from left to right, meaning that, if you look at the Earth so that you can see America, Africa and Europe, then the world rotates so that America (on the left) moves towards Europe and Africa (on the right). Alternatively, if you imagine yourself looking down on the Earth from above the North Pole, then the Earth will spin anti-clockwise, and it does this once a day. However there are two types of day - a solar day and a sidereal day. A solar day lasts 24 hours, and this is the time taken for a given point on the Earth to spin around so that it is once again facing the sun. Whilst the Earth is rotating, it is also moving along in its orbit around the sun. As it takes 365 days to compete its orbit, during which it goes through 360 degrees, it travels through an angle of just under 1 degree per day. The time taken for the earth to turn on its axis through 360 degrees is 23 hours, 56 minutes 4.1 seconds. This means that if you look at a particular point in space, e.g. at a star, then 23h 56m 4.1s that star will be in the same position in the sky. This is a sidereal day (from the word for "star") The Earth needs to then turn an extra degree to line up with the sun again, and the extra few minutes take us up to 24 hours. As the circumference of the Earth is 40,075.02 km (24,908.79 miles) around the equator, then any point on the equator is traveling at 1,674.36 km/hour, or 1,040.62 miles/hour!

Do all places on the earth have the same average speed?

Assuming the question is asking about the Earth's rotation, it depends upon how you measure speed. If you measure angular velocity, then yes, every point on earth rotates at the same speed. If you measure linear velocity, then no, points near the equator rotate faster than points near the poles. Still in linear velocity, points at higher altitude rotate slightly faster then points at the bottom of the deep ocean.


How the earth movements affect climate?

earths axis is little tilted which makes its rotation different at different points of time. this change in rotation and the significant difference of distant between the earth and the sun affects the climate


What is the meaning of angular line?

angular line are the straight lines and sharp points contain in any things....


What is meant by angular points of a rectangle?

Basically, angular points of a rectangle refer to the vertices in itself. They are so - called because at the vertices, an angle is formed. Any other point on the line is simply called a 'point' but the point where an angle is formed is called as 'Angular point'.


What is the tilt of the earths axis of rotation?

Approximately 23°. As a matter of interest, the Tropics of Cancer and capricorn are 23° from the Equator, these representing the most northerly/southerly points on the Earth where the Sun can be directly overhead. This is due to that tilt of the earth.


What is the outward from the center of rotation?

I think you mean the centrifugal force. That force points outwards from the center of rotation.


What are the two factors that cause the earth's seasons?

rotation of earth -earth is at a tilt so sometimes some parts get more sun then others rotation around the sun -earth will be at different distances from the sun as it rotates around


How is the angle of magnetic declination measured?

You need to determine the geographic north, for example by observing sunrise and sunset; by observing the stars; or by using a compass that reacts to Earth's rotation (a gyrocompass). Then you observe where the needle of a magnetic compass points. Finally, you measure the angular difference between the two.
