Question

Describe at least two ways that gravitational and strong nuclear forces are alike and two ways that they are different.

Answer 1

@random231

Answer 2

This is my answer:

Gravitational force attracts objects due to their mass. Strong nuclear force holds protons together in an atomic nucleus. Both forces attract. Strong nuclear force only applies to protons while gravity applies to all matter.

I just need to know one more similarity between both forces.

Answer 3

1 similarity is that both attracts

Answer 4

I already wrote that.

Answer 5

but @micahpkay its not right that it only attracts protons

Answer 6

What do you mean?

Answer 7

actually strong nuke force affects quarks(u probably dont know wat it is)so it affects neutrons too

Answer 8

Ohhh. That was a mistake. I meant atoms.

Answer 9

well another similarity can b that both forces act between two or more bodies

Answer 10

And I forgot to mention, I also need to know another difference between both forces.

Answer 11

it is not possible for any of the force to act on one particular body

Answer 12

Okay.

Answer 13

Gravity has an inverse squared relationship with distance between the objects whereas strong force has a different relationship which drops off much faster that 1/r^2, As such strong force effect is limited to very small distances whereas gravity effects are on the astronomical level.

Answer 14

Wallach, were you going to say something?

Answer 15

I don't know if it helps but their equations are really much the same because they react the same way.
Newton's gravitational law : \[F = G*\frac{ m_{1}*m_{2} }{ r^{2} }\]
Coulomb's Law: \[F=K*\frac{q _{1}*q_{2} }{ r^{2} }\]

as you can see both forces react the same way to distances

Answer 16

So you're saying that distance affects the strength of both forces?

Answer 17

yes and in the same way

Answer 18

And a difference is that gravity has a farther range than strong nuclear force.

Answer 19

sorry *coulombs force

Answer 20

If it isn't a nuclear force, why is it called strong NUCLEAR FORCE?

Answer 21

oh haha

Answer 22

strong nuclear force isnt coulombs force is it?

Answer 23

if I remember correctly the strong nuke it the force between the positive and negative parts of the atom, but I'm not sure (I didn't touch this subject for a long time). if it's so than its an electric force that work as written above

Answer 24

I don't understand.

Answer 25

lets google search.... hue hue

Answer 26

By the way, I'm not taking a Physics class. I'm taking Physical Science.

Answer 27

but I can say that I'm sure there's an equilibrium point between the 2 forces that most atoms aspire to reach (in a perfect world, you know)

Answer 28

nah wallach its not coulombs force tho its the attraction between charges
it has some pi meson complicacy......ughhh nuke physics

Answer 29

Can one of you please tell me a similarity between gravitational force and strong nuclear force?

Answer 30

I told u its a force that occurs between two or more bodies

Answer 31

i mean both

Answer 32

you're right it's the force holding the nucleus together. sry my bad

Answer 33

well second similarity is simple

Both are NON contact forces :D..

Answer 34

lol that could help :)

Answer 35

:)

Answer 36

What about a difference?

Answer 37

you had them didnt u?

Answer 38

oooo oooo i got one

Nuclear works in the short range
Gravitation works in long range

Answer 39

Another one?

Answer 40

oooo oooo ooo

no.. you ge the rest :P

Answer 41

I really need to know! I seriously can't find it anywhere, even in my lesson.

Answer 42

just think about the two forces, if you cannot find any other difference, then clearly you haven't understood them :P..so review them.. if i directly tell you the answer.. then the purpose of the question is lost, and you lose the chance of learning .. do you really want that??
now do you??
huh?
i don't think so..

so chop chop mister..!..

Answer 43

yeah better atleast google search and read about them!!

Answer 44

I did Google it. For an hour. My lesson doesn't even tell me much about the four forces. Would you please just tell me? You can explain your answer.

Answer 45

@Mashy

Answer 46

ermm.. ok.. do you know if nuclear force obeys the inverse square law?

Answer 47

No, I do not. I am taking Physical Science, not Physics, so I am not supposed to learn about that stuff yet.

Answer 48

ermm.. hmmph.. ok

if protons put nuclear force on protons, shouldn't they just go and crash into each other?.. why don't you think they crash into each other?

Answer 49

Strong nuclear force holds the contents of an atom together.

Answer 50

yea.. true.. but why don't they crash into each other? do you know of that?

seriously.. i dunno why they are asking you this difference.. for physical science :P

Answer 51

No.

Answer 52

well.. nuclear force tends to become repulsive at very very short distances, and is attractive at lil distances, and vanishes at far distances..but gravity is always attractive

Gravity obeys inverse square law, which means, the force goes down as one over square of the distance
ex. if you go twice as far, the force goes down by a factor of 4 and not 2
similarly if you go thrice as far, the force goes down y a factor of 9 not 3.. and so on
but nuclear force doesn't obey that nice dandy relationship.. its a pain in the behind and is really complicated to deal with

Answer 53

Nuclear force is the strongest force in the universe

Gravitational force is the most pathetic and weakest force in the universe!!

Answer 54

i mean, the entire earth is attractive that mouse you are holding right now, towards the centre of it.. and how much force it takes to counter it? nothing.. nothing at all
gravity is that weak.. shame on you gravity.. SHAME ON YOU!!!!

Answer 55

So that is a difference?

Answer 56

i just mentioned .. see :P
