Gravity is the most effective over long distances.
no
Gravity between any two particles is much, much weaker than the strong force, the weak force, or the electromagnetic forces.However, note that gravity acts over long distances, and particles attract each other, they don't repel each other, through gravity. Therefore, the cumulative effect can be considerable, and gravity is a very powerful force on large (astronomical) scales.
Non-Contact ForcesWhile the ball is in the air, one force acting on it is gravity. Gravity pulls the ball down to the earth without touching it. This means it is an example of a non-contact force, or a force exerted on an object that does not make contact with it. Another example of a non-contact force is magnetism. Read more about magnetism.
Because (1) It extends to arbitrarily long distances, unlike some other forces. (2) Unlike electricity and magnetism, which also extend to arbitrary distances, it is always attractive. The result is that the (tiny) contributions of lots of individual particles contribute to one great force.
Short distances Medium distances and Long distances
A long range force is one which exerts a noticeable or large influence at considerable distance from the object which generates it. The best example is the force of gravity. The gravitational influence of the sun, for example, can be felt even a billion miles away from the sun. That is a pretty long range.
It acts at long distances.

Forces hold the Universe together. On a closer to home base, the forces also hold our solar system together, allowing us to ask questions on Answers.com. (Gravity exerts a weak force the works from long distances, EM exerts a strong force that works from long distances, and Nuclear forces would take too long to explain.)
Similarities: Both obey an inverse-square law, and, it seems, extend to an arbitrarily far distance.Differences: Gravity is always attractive; gravity is much weaker for individual particles, but because it is always attractive, the overall effect at long distances, and for large masses, is predominant.Similarities: Both obey an inverse-square law, and, it seems, extend to an arbitrarily far distance.Differences: Gravity is always attractive; gravity is much weaker for individual particles, but because it is always attractive, the overall effect at long distances, and for large masses, is predominant.Similarities: Both obey an inverse-square law, and, it seems, extend to an arbitrarily far distance.Differences: Gravity is always attractive; gravity is much weaker for individual particles, but because it is always attractive, the overall effect at long distances, and for large masses, is predominant.Similarities: Both obey an inverse-square law, and, it seems, extend to an arbitrarily far distance.Differences: Gravity is always attractive; gravity is much weaker for individual particles, but because it is always attractive, the overall effect at long distances, and for large masses, is predominant.
Gravity and elastic force...
Yes. Gravity is a constant force. It never changes as long as you are within it's pull.
Gravity. Specifically, the gravity of the Sun.
There CAN be, as long as the force is being counterd by an equal and opposite force.
as long as sun doesn't changes its gravitational force
