Frequent question: What is gravity attracted to?

Gravity attracts anything with a mass (energy), i.e. electron, proton and neutron all feel gravity. But the fact is that gravity is very weak compared to other 3 kinds of known forces (weak, electromagnetic, and strong).

How does gravity attract an object?

Gravity is the reason things with mass or energy are attracted to each other. … The reason gravity pulls you toward the ground is that all objects with mass, like our Earth, actually bend and curve the fabric of the universe, called spacetime. That curvature is what you feel as gravity.

What is gravitational attraction affected by?

When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.

Does gravity always attract?

Gravity is always attractive force because as is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915) which describes gravity not as a force, but as a consequence of the curvature of spacetime caused by the uneven distribution of mass.

How is light attracted by gravity?

According to general relativity, gravity is actually caused by a curving of space and time. Since light travels in a straight line through straight spacetime, the curving of spacetime causes light to follow a curved path.

How does mass affect gravitational attraction?

Gravitational force is an attraction between masses. The greater the size of the masses, the greater the size of the gravitational force (also called the gravity force). The gravitational force weakens rapidly with increasing distance between masses.

Which depends on gravity?

Newton. Which depends on gravity? Weight.

How does gravity behave like magnetism?

The idea that the Earth pulls on objects is difficult for many students. … A useful analogy for explaining the Earth’s gravity force is that the Earth can pull on objects without touching them just like a magnet can affect other objects without touching them.

Does gravity attract energy?

Gravity attracts any form of mass or energy, including all fundamental particles, photons, and even kinetic energy.

Does mass attract gravity?

Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.

Is gravity 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 [3].

Can gravity attract photons?

Since light (whether perceived as a ray or a photon) has no mass, Newton’s equation predicts that it will not be attracted by gravity towards anything, no matter how massive.

Is lightning affected by gravity?

Yes,but the force of gravity is too small compared with electromagnetic forces. I don’t think lightning goes up against mass.

What are photons attracted to?

Ordinary matter primarily interacts via the electromagnetic force: electrons repel each other and are attracted to protons, thanks to their electrical charges. Photons, on the other hand, are both electrically neutral and massless in free space.
