Relative motion under classical mechanics theory. Car is riding on Earth in direction from equator to north pole. Road of car's movement is parallel to meridian. As we know Earth rotates with period of 24 hours. Earth also travels around the Sun with period 365 days and 6 hours on trajectory which is elipse. Subject of example is to calculate absolute velocity of car. Absolute velocity has components. First component is tied with car's move on Earth. Second component is tied with Earth's rotary motion. As we know Earth is not ideal orb. In this example we will treat Earth as an ideal orb. Earth also executes precession movement. In this example we will omit precession movement.
