How does the earth's linear velocity and angular velocity change? We only know that the velocity decreases with the increase of latitude,

The angular velocity of the earth's rotation is the angle of rotation per unit time. Because the earth's rotation is around the earth's axis, the earth's axis itself does not rotate. In this way, the angular velocity of the north and south poles on the earth's axis is zero. In other places, regardless of the length of the latitude coil, a rotation around the earth's axis has passed 360 degrees, which takes about 24 hours
