does te distance from the sun seem to affect the amount of gravity on the planets? give two reasons.?

Answer 1

Um, there aren't two reasons -- there's only one.
Yes, distance from the sun affects the amount of gravity on the planets. The ONLY reason is because the force of gravity is an inverse-square function: every time you move twice as far away from the sun, the force of gravity is one-fourth as strong. In other words, the strength of gravity varies as the inverse square of the distance from the source of gravity.

There *isn't* another reason...

Answer 2

No, I don't think so. The gravity of a planet is determined by its mass, not the sun's mass. If the Earth were floating by itself in space with no sun anywhere, your frozen butt would still weigh the same.

The sun's gravitational influence on a planet in our solar system is much weaker than the gravitational influence felt standing on the surface of that planet. Gravity is all about (1) mass and (2) distance from the mass.

Answer 3

The force (F) of gravity between two bodies in dependent upon the mass (m) of each and inversely upon the square of the distance (r) between them.

F= G *m1* m2/ (r^2)

So the two reasons are :
1. Mass of the sun and planets
2. Distance between sun and planets

Answer 4

Well Travelled is spot on and there is only one reason. The gravitational attraction between two bodies is inversely proportional to the square of their distance apart. In other words if they are 4 times further apart the gravitational attraction is 16 times less than when they were 4 times closer together because 4x4=16. Inversely means as one parameter increases the other decreases. So as the distance between two bodies increases the gravitational attraction decreases according to the square of the distance between them. Easy peezy.

Answer 5

No! The mass of the planet does.
Earth and Jupiter. You have got me on the second reason!
