Let me try to explain myself better. Earth’s circumference is roughly 40,075 kilometers. A point on Earth’s surface at the equator covers that distance in 23 hours and 56 minutes, meaning it is traveling at around about 1656 kilometers per hour. Mars’s circumference is roughly 21,344 (a little over half the size of Earth), but it’s rotational period is actually longer than Earths by close to 40 minutes. A point on Mars’s surface at the equator is therefore traveling a little over half the distance that our point on Earth is, in a little over the same amount of time. Therefore, it is spinning much slower. 868.22 kilometers per hour to be precise, a little over half the speed.
If Mars were the size of Earth but still spun at the same speed, its day would be over twice as long as Earth’s. If it was the same size but spun as fast as earth did, it’s day would be a quarter the length of Earth’s.
Yeah but that is only the velocity vector of a point on the surface, which says nothing about the day length.
Since you do not notice this velocity vector because it does not affect your own relative velocity, in other words everything around you moves along with you on this vector it is less useful to describe the planetary environment.
This does effect things like gravity though, the faster some planet spins the lower the gravity because the
centrifugal force vector opposes the gravitational force vector.
Also the mass of the planet of course determines the gravitational force. On the moon it is only about 1/8 of earth for this your body only weighs 10 kg if it weighs 80 on earth. So you can jump incredible wide and high.
