What is the Law of Gravity and Why Do Masses Attract?

In summary, mass attraction is caused by the force of gravitation, which is a long-ranging force between bodies. For small particles like the nucleus in an atom, there is also a nuclear force that helps with attraction between subatomic particles, but it is a short-ranging force. The force of gravitation is also known as gravity, and while we have theories that can explain how it works and make predictions, we do not fully understand why it works. This question falls more into the realm of philosophy.

What causes mass attraction?
Please expalin it so that its easy to understand?

The force of gravitation causes attraction between the bodies. it is a long ranging force.
for small mass particles like nucleus in atom there is nuclear force which is helpful attraction between subatomic particles. THESE ARE SHORT RANGING FORCES.

But what is that force ?
How does it attrac?

It's called gravity. If you want to know how it works, pick up a book on general relativity. If you want to know anything beyond that, I recommend moving this to the philosophy section.

So what you are saying: we don't no except ist called gravity ?

No... what I'm saying is we can describe very well with our theories how gravity works. We can make predictions about what will happen because of gravity. But we cannot really tell you why gravity works. Take for example the explanation of General Relativity that mass curves space-time, and objects simply follow geodesics in this curved space-time, resulting in what we traditionally think of as the gravitational force. Now this is a great model for predicting things, but it says nothing about why mass curves space-time. This is what I meant, because that question is more the subject of philosophy.

masses tend to attract as that is the law of gravity ,and gravity is aforce
 

1. What is mass attraction?

Mass attraction, also known as gravity, is a fundamental force of nature that causes objects with mass to be pulled towards each other.

2. What causes mass attraction?

Mass attraction is caused by the curvature of spacetime caused by the presence of mass. The more massive an object is, the more it curves the spacetime around it, causing other objects to be pulled towards it.

3. How does mass attraction work?

Mass attraction works by the principle of mass-energy equivalence, as described by Einstein's famous equation E=mc^2. This means that mass is equivalent to energy, and objects with mass have a gravitational pull on each other due to their energy.

4. Does mass attraction only occur between large objects like planets?

No, mass attraction occurs between all objects with mass, regardless of their size. However, the strength of the attraction is dependent on the mass and distance between the objects.

5. Can mass attraction be explained by other theories or phenomena?

Currently, mass attraction can only be explained by the theory of general relativity. Other theories or phenomena have been proposed, such as modified Newtonian dynamics, but they have not been able to fully explain the observations and measurements of mass attraction.
