Why is gravity a force? Why do some materials combust when they meet each other? Post a force like fire, gravity, etc. and tell properties about it that really are strange. ( ex. why don't water and oil mix?) No gory or gross topics.
I think what the one who made this post means, examplethis is really difficult to understand think it alot)
If i have two containers touching each other, in one ive got ice and in the other ive got hot oil. Obviously because they r togheter the temperatureswill get to a medium point the ice will melt and the oil would be more cold.
But, without touching anything, can they get back to what they were?? can water be ice again or the oil get hot again alone??
Oil does not mix with water, because oil is much, much thicker. When you are done stirring and leave it sit, the water will actually rise above the oil and sit on top of it as though it was completely untouched! Fascinating, really...
That is not right. At all. Different oils have different densities, some are heavier, some are lighter than water. They are immiscible with water because oils are nonpolar substances while water is polar. Polar and nonpolar liquids are not completely miscible.
That is not impossible, its just reeeeeally unprobable but can happen, physics just tell us what normally happens with certain things but they cannot be always be right. Another example, ive got a box with a puzzle, i trough it to the air and the pieces join alone and fall with the ouzzle ended perfectly
Is that possible???
YES, it extremely rare that something like that happens, but not impossible!!!
The first thing when u study about phsycis is that u can never be 100% certain theres always a 0,0000000000000000000000000000000001% of probability that what u stated is wrong!!!
Yeah, the famous Schrodinger's Cat experiment. It's mind boggling that quantum probability plays such a vital role but at the same time absurd.
hat is not right. At all. Different oils have different densities
By the way, I do agree with Gantic, but what Freakenstein said was correct as well. To an extent the viscosity of the oil does prevent the mixing of water with it apart from the fact that their densities are different.
I don't believe that fire is considered a force in physics.
The equation of force in physics:
F= dp/dt F= d(mv)/dt F= m dv/dt F= ma
F = force (the net vector sum) p = the momentum of the system m = mass v= velocity a = acceleration
(The vector quantities are given in bold.)
The law of universal Gravitation:
F = G m1m2/r^2
F = the magnitude of the gravitational force between the two masses (considered as points) G = the gravitational constant (6.67428 x 10^-11 N(m/kg)^2) m1 = the mass of the first point mass m2 = the mass of the second point mass r = the distance between the two masses
The acceleration due to gravity on Earth is approximately g = 9.807 m/s^2
Fire however is a chemical process of combustion. Combustion reactions can produce energy in the forms of heat (flames) and light can be given off (from the flames)
Physics and math seem to be a set of "definitions" often expressed by equations that are given in order to understand the universe around us. It's all as well that when the Arabic numeral system was invented (0123456789) 4 could Have been 3 and 5 could have 8. Then as a whole humans would have just used the symbol 8 to represent what is considered 5 in this reality. It seems strange to think of it like that of you counted 1 2 3 4 8 6 7 5 9 0, but if the system were like that in the beginning no one would think of it as strange because no one would have another system. Think of 2 is represented by this symbol 2 and this totally different symbol II (Roman numerals) but you understood both of those meant two (two another symbol for 2).
Why are electrons negatively charged and protons positively charged?
When they were discovered they could have been given different names, but in essence they would still act the same way, not to mention antimatter.
positrons (the antiparticle of the electron, which is positively charge ) antiprotons (the antiparticle of the proton, which is negatively charged) antineutrons (the anitparticle of the neutron, which is a neutrally charged)
Why isn't the world made of antimatter instead of regular matter? The numbers are symbols are a approximate representation of what is going on around us and are a way of conveying ideas and thoughts in an easier more universal way to understand.
People eventually ran out of cake and had to cure their boredom with silly drawings on chalkboards explaining how their mother has a gravitational orbit.
Chemistry, however, is when the few dared to try and make more cake.
Oops! You made me remember The Great Divide. Sadly, most sided with the disco'ers trying to find the perfect jam for finger-waving and hip thrusts.
To quote the great Doctor Steven Brule - "As a doctor I should be able to tell you the causes of diahhrea, but unfortunately... It is one of the greatest mysteries... to the scientific world."
Who needs poison when you have frosting? Camman sonic! think!
here's one thing i don't get. how can you disprove something, IF THEIR'S NO PROOF IN THE FIRST PLACE..."
There is proof of some physics and other things are just theories.
If you lite a match in an oxygen enriched environment you will get at the least a fire at the most an explosion. It can be proven over and over again. If it is repeatable and you never see any deviation from that in your results therefore it is considered a fact.
Facts are facts until they are proven wrong. You can accept that the fire will happen over and over and accept it as a fact or you can spend the rest of days trying to disprove it.
The standard model that we currently use explains a lot of what we see happen in the universe. Of course Newtonian laws of gravity worked perfectly well with the exception of a few things. As we learned more new theories had to be come up with. As our technology and understanding of things increases. We will continue to evolve our facts until they can explain everything all of the time. Heisenberg's uncertainty principle state's that we not know both somethings position and momentum at the quantum level. This will be true until someone devises a way to measure it.
Physics is a field of study that is all about disproving a theory. We have physics to try and understand what we see, because we are curious creatures. If you think a theory is wrong then prove it wrong. Otherwise accept it. Science has a certain aspect of faith in it. Which is one of the reasons religions long ago tried to ban it. faith in our observations versus faith in an almighty and the religious leaders were at odds and to a certain extent still are.
@Reton8: What you said sounds and look UBER smart, but its just grade 11 physics :P Oh and is it universal to bold vector quantities, cause ive seen multiple people/books do that
and fire is not a force, it is the reaction of a material with oxygen (in the air) and the reaction is exothermic so it gives off energy (in the form of heat and light).
