SUMMARY

The discussion confirms that the tangential acceleration of any point on Earth is indeed 0 due to the Earth's constant rotational velocity. Participants referenced the use of normal and tangential coordinates to analyze motion, emphasizing that since the Earth rotates uniformly, there is no change in tangential speed, resulting in zero tangential acceleration. This conclusion is based on fundamental principles of rotational motion.

Using normal and tangential coord the the tangential acceleration of any point on Earth is 0, correct?

Normal and tengential, coord? I don't quite know what you mean by that, but you are right that since the Earth spins with a constant velocity, there will be no tangential acceleration.
