Why does earth have gravity and other planets don't?
The other planets do have gravity.
Why does earth have gravity and the other planets do not?
All massive objects (including all planets) have gravity.
Why is there only gravity on earth and not any other planet?
All planets have gravity, not just Earth.
What holds Earth and the the other planets in their orbit?
Gravity
Is mass affected by gravity on earth and other planets?
No. Weight is affected by gravity.
What forces holds the earth and other planets in the Sun's orbit?
Simple. Gravity! The planets are dragged in by the gravity of the sun.
Does earth have the most gravity compared to the other planets?
No. Of the planets in this solar system, Jupiter, by far, has the strongest gravity.
Does earth have strong or weak gravity?
Because of Earth's size, and considering it as one of the smallest planets, it has a weak gravity compared to the OTHER planets. Most planets have greater gravity because of their size. Earth has a stronger gravity compared to mars, mercury, and venus.
How does the gravity of the sun impact on earth?
The sun's gravity keeps the earth and the other planets in orbit around it
What is gravity and how does it affect planets and the oceans?
'Gravoty' is an attraction between any two or more objects, be those objects atoms, protons or planets. stars andything in between. The planets have gravity , the Sun has gravity. They are attracted to each other. So why do they not 'crash' into each other? Because, the planets are moving with an acceleration. This acceleration together with the planets mass creates are force (F = ma). This force is balanced by the Sun's force of gravity. So the forces are in balance, so the planets orbit the Sun and not fall into the Sun. The oceans on Earth, being liquid, will be attracted to the Moon by Lunar gravity. So which side of the Earth the Moon is on , will be the 'High Tide'. This is balabnced 'Like a wheel balance', by a counter High Tide on the opposite side of the Earth, from the Moon.
What affect does gravity have on the planets?
The planets' own gravity has made them spherical. Also there are other effects such as their ability to retain an atmosphere, etc. The Sun's gravitycauses the orbits of the planets.
Why don't any other planets have any air and gravity?
All planets have gravity- Some more than Earth, some less. Other planets that are large enough do have air- but not made up of the same gasses as Earth.
