Apr 22, 2017 · Gravitational wave carries energy and momentum, gravity is still attractive. When the gravitational wave hits something or gets absorbed by something sure it'll transfer momentum. An electromagnetic wave does the same, but it is by itself neither attractive nor repulsive.
If there were repulsive gravitational forces, it would imply that the body has negative mass which is not possible. Hence, gravitational forces are always attractive in nature. The gravitational force between two masses m 1 and m 2 at a distance r is given as, Gravitational force, F G = G m 1 m 2 r 2 where, G is the universal gravitational ...
Dec 16, 2023 · The gravitational force is surprisingly weak—it is only because gravity is always attractive that we notice it at all. Our weight is the gravitational force due to the entire Earth acting on us. On the very large scale, as in astronomical systems, the gravitational force is the dominant force determining the motions of moons, planets, stars, and galaxies.
Jul 28, 2017 · Theoretically, gravity can be "attractive" in the sense that objects move towards you when pushed. This can occur from negative mass (doesn't seem to make sense, but theoretically possible). Peter Engels and others have written a paper about it here and it's an interesting idea.
Jun 10, 2009 · All the other forces in nature have opposites – so what makes gravity different? ... “The strong nuclear force is attractive at some distances and repulsive at others.” ...
Gravity is an attractive force that draws two objects together. Its strength approximately increases with the masses of the two objects but decreases with the square of the distance between them. That means that if the Moon were twice its current distance from Earth, the gravitational tug between the two would be just one fourth of what it is now.

Nov 10, 2024 · The force between opposite charges is attractive, whereas bodies with the same kind of charge experience a repulsive force. Coulomb also showed that the force between magnetized bodies varies inversely as the square of the distance between them. Again, the force can be attractive (opposite poles) or repulsive (like poles).
