Axis
If the hole passed through the DIRECT center of the earth, it will stop when it reaches the DIRECT center of the earth, it will do this because the are equal amounts of gravity forcing being applied on each one of the infinite sides of the circle.
The imaginary line that extends straight out from the center of a reflective surface is the optical axis.
Axis of rotation
Yes. Earth does acomplete spin on its axis, or the imaginary line drawn through the center of the Earth, once every 23 hours and 56 minutes. The side facing the sun gets day and the side facing away from the sun gets night.
The earth rotates on it's axis, the imaginary line that runs from the north pole to the south pole through the center of the earth.
The earth rotates on it's axis, the imaginary line that runs from the north pole to the south pole through the center of the earth.
The earth rotates on it's axis, the imaginary line that runs from the north pole to the south pole through the center of the earth.
Axis
Axis of rotation is an imaginary line about which a turning body rotates. Or the center around something rotates.
A planetary axis is the imaginary line or pole through the center of the planet which defines the point around which the planet rotates, or spins.
An imaginary line that runs through the center of a planet and its poles is called its axis.Or possibly a diameter, in regards to the planet's dimensions.
The equator.
