There are two ways to do that:
-- Make the product of their masses four times as great.
-- Make the distance between their centers halfas far.

What is the rule for the force of gravity?
The force of gravity is directly proportional to the product of the mass of the two objects ,between whom the force is acting , and inversely proportional to square of distance between them.
Are there forces acting on a car that is at rest?
Yes, gravity is constantly acting on all objects even when they are at rest.
When objects are moved further apart from each other the force of gravity does what?
In classical physics, the force of gravity between two objects is given by the following equation: F = G(Mm/(r^2)) Where F is the force, G is a number called the Universal Gravitational Constant, M and m are the masses of the two objects, respectively, and r is the distance between them. From this equation we see that F, the force is proportional to 1/(r^2). This is known as the inverse squares law. When objects are moved apart, the radius r increases and so the force of gravity decreases in accordance with the inverse square proportionality.
What is Albert Einstein's theory of gravity?
Einstein described gravity as a warping of the fabric of space-time itself rather than as a force acting across it. He imagined space as a 3D representation of a thin rubber sheet, and objects placed upon it as creating indentations that draw other objects into them. The greater the mass of the object, the larger the dent, and the greater the curvature of space around the object. This is the founding priciple of his General Theory of Relativity.
How is gravity different for objects that freely fall down and those thrown upwards?
The gravity acting on a rising object and that on a falling object are the same when these objects are at the same height. What is different is that a rising object is decelerating by the force of gravity and the falling object is accelerating.
What is a force acting between two objects?
gravity
Is gravity a core in the center of the earth?
No, gravity is a force of attraction acting between all objects that have mass.
Why do objects with more have greater weight?
weight is the effect of gravity acting on mass,the greater the mass the greater the effect on gravity will have on it therefore the greater the weight. eg. if the mass is 50kg and gravity is 10N the the weight is 500N,if the mass increases to 100kg the the weight would increase to 1000N
Why do objects with more mass have greater weight?
weight is the effect of gravity acting on mass,the greater the mass the greater the effect on gravity will have on it therefore the greater the weight. eg. if the mass is 50kg and gravity is 10N the the weight is 500N,if the mass increases to 100kg the the weight would increase to 1000N

The forces acting on objects falling near the earths surface are?
Mainly gravity, and air resistance.

What force is acting if you fall from a bike?
gravity it pulls all objects down
When the only force acting on a falling object is gravity the objects is said to be?
= Terminal velocity =
Are there forces acting on objects at rest?
Yes there is air force, Gravity, his weight etc.
What is the reason behind gravitation?
Based on Einstein's theory of relativity, spacetime is curved around massive objects, and gravity "acting" on objects is actually just the objects following this curve in spacetime. Gravity is not a force.
