What The effects that causes objects to a move in a curved direction due to earths rotation?
It's called Coriolis force.
Why does weight on an elevator change though you don't leave earths gravity?
If the elevator accelerates, the acceleration will provide an additional apparent force.
Does the earths rotation speed up from the moon?
No. Just the opposite. The earth's rotation is slowing down because of the gravitational force between the earth and the moon. The day is getting longer by something like a millisecond (0.001 second) every hundred years.
What aspect of the earths shape is evidence of its rotation?
The diameter at the equator is larger, by about 1/300, than the diameter from pole to pole. This can be considered a result of the so-called centrifugal force (a ficticious force, but it makes many explanations simpler).
Why does the Coriolis force occur?
The Coriolois force on an object is an "apparent" force that acts on a moving object when observed from a rotating frame of reference. Example, suppose you shoot a bullet from the center of a rotating merry-go-round at someone standing on the rim. If the merry-go-round is spinning fast enough your bullet will miss. Someone standing on the ground says you missed because by the time the bullet got to the target, the target had rotated out of the way. But someone on the merry-go-round says "no, the target didn't move but the bullet curved away from the target, as if a force acted on it". The value of the Coriolis force is 2mvwSin(A), where; m is the mass of the moving object, v is its velocity, w is the angular velocity of the rotating reference frame, and A is the angle between the direction of v and the direction of the rotation axis (up for CC rotation). The direction of the Coriolis force is perpendicular to the plane formed by the direction of v and rotation axis, in the sense found by curling fingers of right hand from v towards rotation axis and your thumb will point in direction of the force. In the merry-go-round example angle A would be 90 deg, so Sin(A) = 1. I gave no rotation direction for merry-go-round so you can't tell if bullet will go to the left or right of target.
What is the name given to the force of the earths rotation?
Centrifugal force.
Is it true that tides are created by the difference between the gravitational force at Earths surface and at Earths center?
Yes, that's basically what causes tides. ===================== And the moon. Lets not forget its role.
How does the force of gravity affect the direction of motion of the planets?
earths rotation around the sun
What is the effect that causes objects to move in a curved direction due to to earths rotation?
It's called Coriolis force.
What The effects that causes objects to a move in a curved direction due to earths rotation?
It's called Coriolis force.
What is the effect that causes objects to move in curved direction due to the earths rotation?
Easy it's the coriolis force
What is the effect that causes object to move in a curved direction due to the earths rotation?
It's called Coriolis force.
How does rotation affect the value of gravity at the earth surface?
The (centripital) force due to rotation is at its greatest at the equator, if you weigh 100 kg, the force of gravity on you = approx. 982 n anywhere on earths surface, the centripetal force at the equator = 3.4 n
Why does weight on an elevator change though you don't leave earths gravity?
If the elevator accelerates, the acceleration will provide an additional apparent force.
Can centripetal force produce rotation?
no, but rotation can produce centripetal force
What are Causes or driving forces that affect currents in the ocean?
The main driving force is wind, but it is also affected by the earths rotation, solar energies, and gravity.
What force keeps the planets in rotation?
The force that keeps all of our planets in rotation is gravity.
