The polar axis is a line through the poles of a sphere or spheroid, especially the Earth's axis of rotation. In Japanese, it is expressed with technical terms or descriptive phrases depending on context.
The imaginary line through the North and South Poles around which the Earth rotates.
Standard term for the Earth's axis of rotation. Used in geography, astronomy, and everyday contexts.
地軸は約23.4度傾いている。
The Earth's axis is tilted at about 23.4 degrees.
Literally 'polar axis'. More technical, often used in astronomy or when referring to the axis of any celestial body.
この望遠鏡は極軸が正確に調整されている。
This telescope's polar axis is precisely aligned.
The line through the poles of any spherical or spheroidal object, such as a planet, moon, or model globe.
General term for the polar axis of any celestial body or spherical object.
火星の極軸も地球と同様に傾いている。
Mars' polar axis is also tilted like Earth's.
Means 'axis of rotation'. More general, can be used for any rotating object, not necessarily through poles.
この球体の回転軸は垂直だ。
The axis of rotation of this sphere is vertical.
In mathematics, the polar axis is the fixed line in a polar coordinate system from which the angle is measured.
The standard term in mathematics for the polar axis in polar coordinates.
極座標では、極軸からの角度で点の位置を表す。
In polar coordinates, the position of a point is expressed by the angle from the polar axis.
