is that correct................gravitation force?

Question

is this correct that :whenever we increase the width the gravitation force increase and vice versa...e.g: 2 objects with same weight a&b>a is wider than b>that the gravitation force is more in a than b

Answer 1

The person who said that gravitation force is a function of mass and not how wide the object is IS WRONG. Because the force is not only a function of mass but also the distance.
So shaping your objects differently, for example making them wider, could possibly place parts of these objects closer to each other and, as result, make the force stronger, also depending, of course, on how you position/rotate these objects relative to each other.

Answer 2

I agree BabyMD.Gravitational force F=GmM/r^2. It depends on mass of the object m, distance between the two object r, Mass of earth which is constant M, G gravitational constant. If any of these changes Gravitational force changes. In ur example, When u say width changes then u have to think which of the above will change it will be Mass right. Thats why gravitational force will change.

Answer 3

I'm a bit confused by your question - whenever you talk about gravitational force, you must always talk about the force *between* two objects. Nothing possesses gravity.

Are you talking about the gravitational force between a & b? If so, the force only depends on their masses and the distance between them (specifically, the distance between their centers of mass).

Are you talking about the gravitational force Earth exerts on two different objects, a & b? Here, too, the force depends only on their masses and their distances between their centers of mass and Earth's center of mass.

Are you talking about two planets, perhaps Earth and another (hypothetical) planet of the same mass but different radius, and how much an object would weigh on each world? In that case, the size of the planet would matter, since an object can get no closer to the center of mass of the planet than the planet's surface. So someone who weighs 150 pounds on Earth would weigh less on a world that is larger but has the same mass, because he would be farther from the center of mass of the planet. (BTW, weight is a measure of the gravitational force between a planet and an object on that planet.)

Answer 4

No. Gravity is a function of mass, so it is not how wide the object is, but how much mass it has. This means that even if you increased the width or any other dimension of the object, but you have not added more mass, the object will exert the same aount of gravitational force.

Answer 5

When you increase the distance between a and b Gravitational force is lessened

When you decrease the distace between a and b Gravitational force is increased

Its like the distance between two lovers a and b when they get closer --- WATCH OUT!!!
