The answer is in general relativity: the gravitation is not a real force, it is apparent: is an inertial force dued to the curvature of space produced by mass-energy. So there is no gravitons nor field particles, nor charges producing a positive or negative force for attraction or repulsion.
Why is gravity a force that can only attract?
Why is gravity only an attractive force? Because mass is always positive. There are different notions of mass, but they’re equivalent. There are two distinct notions of mass: gravitational and inertial.
Do gravity forces attract or repel?
Unlike the Force, with its dark and light sides, gravity has no duality; it only attracts, never repels.
Why does the force of gravity only attract objects while electric force can attract or repel objects?
The electrical force repels (when the charges are unlike) as well as attracts. The gravitational force only attracts. … The charge of protons and electrons are exactly the same size, but the proton is positively charged, while the electron is negatively charged.
How does gravity repel?
Gravity is the mutual attraction of matter and energy. Anti-gravity would imply that matter and energy would somehow mutually repel. If gravity causes two planets to attract each other, anti-gravity would cause them to repel each other. The repulsive force, however, is the property of empty space itself.
Is gravity only attractive?
Gravity is not always attractive: Gravity is thought of as a weak boring force. But if you get fast spinning black holes and strong gravitational waves interacting, then you can get ‘repulsion and attraction’ effects happening out of purely gravitational forces.
Can gravity be both attractive and repulsive?
Both in the Newton theory of gravitation and in the General Theory of Relativity the gravitational force is exclusively attractive one. However, the quantization of gravity shows that the gravitational forces can also be repulsive .
Is gravity an attractive force?
Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.
Why do charges attract and repel?
If a positive charge and a negative charge interact, their forces act in the same direction, from the positive to the negative charge. As a result opposite charges attract each other: The electric field and resulting forces produced by two electrical charges of opposite polarity. The two charges attract each other.
Do like charges attract or repel?
Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge.
What force can only repel?
Electric forces are very large, far greater than the force of gravity. Unlike gravity, there are two types of electric charge, (whereas there is only one type of gravity; gravity only attracts). Like charges repel. Unlike charges attract.
