why you are saying gravitational force is weaker than other forces?

Answer 1

Because it is? Dramatically so.

Look it up yourself.

Gravity is feeble. Just think, the whole earth pulling on you yet you can overpower it by jumping up in the air.

Answer 2

Gravitation seems to be a property of mass, right? Well, the idea is that it would take a very large mass to produce the same force as a relatively small electric charge or a small magnet. Look at a junkyard, for instance. We can make a magnet that will pick up a large vehicle without trouble. I know that magnet seems pretty large, but it's pulling harder than the WHOLE EARTH! In this type of context, you can see that the relative strength of the forces is quite different, and the gravitational force is, in fact, quite weak comparatively. The only reason the Sun can hold all the planets in orbit is because it is so MASSIVE. It would take a magnet a small fraction of that size to produce a magnetic force of the same magnitude...

Answer 3

Of the four known forces that act at a distance, gravity is by far the weakest. Electricity and magnetism (the two halves of the same force) are hundreds of thousands of times stronger. Look at lightning, a beam of pure electricity. It literally can melt any metal and blow-up any water based plant or animal. On the other hand, gravity waves, which emanate from rotating black holes or neutron stars orbiting each other. are the strongest possible gravity beam. After searching for 30 years, we still have not found a certifiable gravity wave because they are so weak, we can not build a detector sensitive enough to detect them, yet.

The nuclear force can unleash an atom bomb or drive the light and heat from a star.

We assign strength or weakness to a force based on the EFFECTS we see from the force.

Answer 4

The force of electrostatic attraction between an electron and a proton is something like 10^40 times greater than the gravitational attraction between them. At greater distances, gravity takes over because the + and - charges cancel each other.

Answer 5

Just think about it. Its easy for you to lift your arm into the air isn
't it? Well by lifting your arm up you are overpowering the gravitational forces created by the Earth. Now get a magnet, and attach it on a surface so that magnetism is the only thing holding it up. The magnetism from the magnet is also overpowering the gravitational forces from the Earth.

Answer 6

Deep blue gave a GREAT answer, but one that may be a little over detailed for the level of knowledge demonstrated by the question.

We experience gravity on a grand scale because of the extreme mass of the planetary and solar objects generating it. Gravity acts on HUGE scales, whereas the other forces act on such small scales.

Answer 7

Gravity, as a force, is far weaker than the other three. For example - the strong and weak nuclear forces can overcome gravity, and attract subatomic paricles very well - but only over short distances.

An electromagnet can pick up a car and move it - overcoming gravity.

Gravity is far-reaching, but it isn't very strong.

Answer 8

Gravity in its own right cannot be actually compared to the other forces of nature (SN/WN/EM). The reason for this is because gravity is its own independent force based off of the mass of objects, and not the content, or state of the object itself.

Instead of saying Gravity is a much stronger force I will venture to say that gravity is much more present force in nature then all of the other 3. Proof: The smallest particles in the universe collided over billions of years to form our galaxy, and solar system.

Answer 9

As far as we know, there are four fundamental forces...
Gravitational Force
Electromagnetic Force
Weak Nuclear Force
Strong Nuclear Force
Each force is carried by a separate "messenger particle" unique to it and still being researched. The strong force is by far the strongest of the forces, followed by the electromagnetic force, the weak force, and finally the extremely feeble gravitational force. Though these four forces govern every matter interaction, a theory that unites them all is still being sought...
Gravity, the weakest of the four forces, is about 10^(-36) times the strength of the strong force. This weakness is easily demonstrable - on a dry day, rub a comb across your shirt to give it static electricity, then hold it over a piece of paper on a desk. If you were successful, the piece of paper lifts off the desk. It takes an entire planet to keep the paper on the desk, but this force is easily overcome with everyday materials employing the electromagnetic force.
However, the range of gravity is unlimited - every object in the universe exerts a gravitational force on everything else. The effects of gravity depend on two things: the mass of two bodies and the distance between them. In more precise terms, the attractive force between any two bodies is directly proportional to the product of the masses and inversely proportional to the square of the distance between the bodies. The dominance of gravity on macroscopic scales is due not to any intrinsic strength but instead to its enormous range and constant attractive nature, especially as compared to the other forces. These properties of gravity have made it extremely difficult to incorporate gravity into modern theoretical frameworks.
The electromagnetic force is actually second in effective strength only to the strong force, but it is listed out of order here because it, like gravity, is more familiar to most people. Its strength is less than 1% of that of the strong force, but it, like gravity, has infinite range. However, unlike gravity, the electromagnetism has both attractive and repulsive properties that can combine or cancel each other out. Whereas gravity is always attractive, electromagnetism comes in two charges: positive and negative. Two positive or two negative things will repel each other, but one positive and one negative attract each other. This can be neatly illustrated by magnets: two of the same "pole" will repel each other, but two opposite poles attract each other.
This is the principle that keeps atoms together: the positively charged nucleus and the negatively charged electrons attract each other. This is also the principle of atomic size: more electrons have greater repulsive force, so atoms with more electrons are larger because of the electrons' mutual repulsion. Similarly, atoms with larger nuclei and the same number of electrons are smaller overall because they exert a greater attractive force on the electrons.
The weak nuclear force is one of the less familiar fundamental forces. It operates only on the extremely short distance scales found in an atomic nucleus. The weak force is responsible for radioactive decay. In actuality, it is stronger than electromagnetism, but its messenger particles (W and Z bosons) are so massive and sluggish that they do not faithfully transmit its intrinsic strength.
The strong nuclear force is the other unfamiliar fundamental force. Like the weak force, its range is limited to subatomic distances. Its "duties" are keeping quarks together inside protons and neutrons, and keeping protons and neutrons inside atomic nuclei. Its messenger particle is the massless gluon, so named because it "glues" elementary particles together.
So i hope i have answered your question......

Answer 10

A great question. I have to accept it because science says it is, however I have a problem understanding why gravity, in the case of a black hole can overcome the force that keeps electrons in place, in a black hole matter is crushed so densely together that there is no space or time. I would like someone to explain why.

Answer 11

Compared to the other three fundamental forces (..electromagnetism, strong nuclear force, weak nuclear force..) gravity is weaker. However, its range is much, much greater than the other three.

"Why" this is so is because that's how our universe has evolved.
