It doesn't.
For instance ... Earth & Venus have almost the same gravity yet Venus' day is about a year long
Whereas Mars has but a quarter of Earth's gravity and its day is almost identical.
Does gravity affect a person's height and why?
I think the length of day affects humans by sleeping earlier or later, they can also be affected by having different emotions. But I think I'm wrong...
During the Autumn equinox the length of the day and night are nearly equal. The length of the day on the equinox is approximately twelve hours.
yes. All the way around the equator the day length doesn't change.
If the Earth's axis was vertical - every point on its surface would have the same length of day and night, no matter what time of year it was. The tilt of the axis (to about 11 degrees) means that, as the Earth rotates, and travels around the sun, the length of day shortens and lengthens throughout the year.
The length of day does not affect the season.
No.
Yes. Given a constant for gravity, the period of the pendulum is a function of it's length to the center of mass. In a higher gravity, the period would be shorter for the same length of pendulum.
18 hours 10 minutes
The length of the day would change if either the rotational speed of the the planet or the orbital distance from the sun changed. However, if you mean what factors affect the length of daylight, then that is different.
If you are in a skidding vehicle, higher gravity will cause shorter skidding length. If you throw an object up in the air, higher gravity will decelerate it more quickly than normal.
no
the tilt of the planet
gravity is something that can affect the planets.
Does mars' gravity affect other objects. yes it does but the gravity is 38% of the earths gravity and if doesn't affect objects then it will have no moon.
Does gravity affect a person's height and why?
Gravity is a function of mass and distance. So, no air pressure does not affect gravity.
