General and Special Relativity

Parent Category: Physics
Relativity is the theory stating that all measurements depend on the relative motions of the observer and the observed. The theories of general and specific relativity were both proposed by Albert Einstein.


No they cannot. This is because while you are applying an upward force on your boots, you apply an equal downward force on your back (and by extension also on your feet and boots). Thus everything cancels each other out. This is a direct consequence of the law of conservation of momentum; if you...
Well, since anti-gravity isn't really an option at this point in time, you're going to need energy to get you moving that is greater than the force of gravity. Since you'll be going up a ramp you will start at a horizontal position before reaching the vertical ascent point. What you will need when...
He hypothesized that the speed of light is constant, no matter what the frame of reference is.
No, Einstein WAS a great scientist in the world.
The best title for your project is one that encapsulates what yourproject is about. It should be short, but still memorable. A goodtitle sets the tone for an entire project, so be sure to spend somegood time on coming up with a title.
Einstein did not invent anything because he was not an inventor.
He helped the US of today by giving us theories that helped explorenew fields of technology.
For some one time goes slower and for the other one the same timemay go faster. If one forgets himself time flies but if one is selfcentered then time goes at very slow rate. This is how public haveunderstood Einstein's theory of relativity.
Albert Einstein's cosmological constant was proved wrong by Hubble as he proved the universe is expanding so it doesn't need a constant to stop it imploding.
Special theory of relativity: 1.The laws of physics are same for all observers in uniform motion relative to one another. 2. The speed of light is same ... Later Einstein proposed General relativity.
Yes it is constant. It never stops moving.
High frequency signals can easily pass through a capacitancecompared to the low frequency. Hence the relation between frequencyand capacitive reactance is inversely related
Entropy is the universe's desire to return to disorder, and is an illusion caused by our perception of time. To picture what's going on in entropy, let's imagine a bunch of gas molecules in a jar. To make things easy, let's picture them as billiard balls. The billiard balls will have a bit of energy...
are you asleep ?
The Higgs field has a non-trivial self-interaction, which leads to spontaneous symmetry breaking: in the lowest energy state the symmetry of the potential (which includes the gauge symmetry) is broken by the condensate. In the simplest example, the spontaneously broken field is described by a...
To figure out the force of gravity between the earth and the moon, you need to use newton's equation of gravitational force, i.e. F=(G x m1 x m2)/r^2 Where F is the force of gravity, m1 and m2 are the masses of the two objects in question, r^2 is the distance between the two objects in question,...
The moon is far enough from the Earth that its environs are essentially an absolute vacuum. No air means no drag.
Never mind young children. There's not one in five reasonably intelligent adults who is able to effectively comprehend the idea of relativity or grasp a few of its implications. That's my opinion. I could be wrong.
Albert Einstein didn't invent the computer he died in the early 1900's before even the weakest computers were created.
Well, first of all, it's going to be darn hard to push the end of that thing a foot from where it is. Let's say you just hit the bottom end with a hammer, causing a loud " CLUNGGG ", and then that sound vibration travels down the pole to the other end. In order to let it move as fast as...
Yes it is..Therotically no object can move in the speed of light.But now scientists are trying to find the conditions for which a particle can move in the speed of light. No, anything massless can (and must!) move at c. No object carrying mass can ever move at c.
In this time line, Albert Einstein is not credited with discovering electricity. Einstein did however do work with the electron's role in quantum physics. In Time Line 3, a man by the name of Albert Einstein did make great scientific progress with electricity in the early twentieth century, however...
The theory of General relativity. Albert Einstein was trying to develop a theory that would better explain why the universe behaves the way it does. At the time most scientists were still using Newton's theories which did not accurately predict the movement of planets around the sun. To explain his...
No, a helicopter hovering in mid air over America will not find itself hovering over India the next day. I think you are wondering if you can suspend yourself somehow in mid air the Earth will rotate beneath you, enabling you to come down to Earth where you like. That would be wonderful, but it does...
the world line of an object cannot leave its own forward light cone because to do so it would have to travel faster than light. once another object enters the forward light cone of an object, it cannot leave it either for the same reason. The backward light cone is a different matter, but it is in...
Lagrangian (L) summarizes the dynamics of the system. Generally, in classical physics, the Lagrangian is defined as follows: L=T-V where T is kinetic energy of the system and V is its potential energy. If the Lagrangian of a system is has been defined, then the equations of motion of the...
It depends on what you mean by leading. A few good candidates are string theory, the standard model and loop quantum gravity.
Quantum mechanics and relativity are both parts of the same puzzle: how the universe works. They are both equally important, because they both explain things that are not explained by classical physics.
A quantum of light is also called a photon. Photons have energy and so must also have mass. This is from the famous equations of Einstein. We know the energy of a photon ... (Planck's constant) times (c)/(wavelength). We know the speed of the photon ... it's the speed of light. We know the...
Answer . Distance covered in nth second means the distance covered in that particular second . It cannot be more than the distance covered in n seconds which means the distance covered in a total time of n seconds.
A refrigerator pump with no moving parts so it did not need seals which wearout and then leak.
See this link for relatavistic mass: hyperphysics Dot phy-astr Dot gsu Dot edu/hbase/Relativ/tdil.html It is not letting me put the link in as normal, so I put the "dots"in. Remember that momentum is conserved. Since initial momentum is zero(since it is at rest) the net momentum of the two...
Definitely not, but using Classical mechanics you should be able to solve this question. Also, I imagine engineers in the field of fluid dynamics might be able to answer your question.
Special relativity is always applicable, but only really useful when you are considering objects moving close to the speed of light. General relativity should be used when objects are very heavy or dense.
When you're in a car and the car suddenly stops (for any reason). You'll feel that you're moving forward, that's why seatbelts are there to prevent you from being thrown out of the car. You being resistant to changes in motion, is an inertia of motion.
We currently do not have any technology to travel outside the "normal" time stream. We are carried along into the future by the currents of cause and effect. Other than moving along with the "present" in the time stream (and, therefore, into the future), no other time travel is within our capability...
Well friction is a force that acts between two surfaces in contact. Although it has unwanted effects like loss of energy or wear and tear, yet it is a very important force and is thus sometimes called 'the necessary evil'. At homes friction needs to be increased on stairs, floors, especially...
Yes, a photon moves at the speed of light, because photons have no mass.
If you go whizzing past me at a high speed, then I'll notice that your wristwatch looks like it's running slow, and the pitch of your voice has dropped. I'll think to myself, "Hey ! I'm OK, but his time has slowed down." At the same time, you'll notice that my wristwatch looks like it's...
This formula shows that matter is just a form of energy; one can convert mass into energy and vice versa.
At present, no, there is no conceivable method of safely traveling in time. Oddly enough, time travel is not prohibited by the laws of physics but there are many obstacles to making it safe or even using it to communicate. In fact, there are hypotheses that state that these obstacles will...
that no one would believe that gandi really existed
Grass is a mixture. In these terms, all living things are mixtures.
It isn't, except for die-hard physics fans!
The photon has no mass so therefore it is dimensionless .
repel force, attraction force,
No one knows but unless you ask Einstein himself we will never know
At least special theory of relativity was published 1905
It depends on how many ppl they have on set so yall jus gonna have to be pation
Einstein was a pacifist and thus against all war. But he was also wise enough to see the horrible consequences to civilization should the Nazis build and use nuclear weapons! Thus when approached by Leo Silard with a letter to FDR recommending research on the bomb, he willingly signed it. Thus...
E=mc^2 is born because of special relativity.
Einstein's Theory of Relativity can be summarized by two points: 1. the speed of light in empty space is a constant independent of the state of motion of the emitting body and 2. equality of relative motion , thus the Theory of Relativity . The first point should explain why light does not...
Of course! Psychologists have problems too, and if their pride allows it, they can get the opinion of another psychologist.
solid reactants form liquid reactants
Never, because he was never an inventor.
E represents energy in Joules, m represents mass in kilograms and c represents the speed of light. Let's say we have a gram of mass. By Einstein's energy equation, that gram of mass has 299,792,458 x 299,792,458 x 0.01b of energy. That works out to exactly 89,875,517,873,681.764 Joules of energy...
Assuming this is a fill in the blank question, relativity undermined the view that time and space were absolute.
Watts, same as light bulbs. Most pen pointer lasers are 5 mw, or 5 milliwatts (5 thousandths of a watt). Image the light of a 120 watt incandescent bulb compared to that. 120 watts vs. 0.005 watts. The light bulb consumes 24,000 times more energy, even though the laser dot is really, really bright.
Special relativity is a fundamental pillar in our understanding of the Universe. Many things are based on it, like the GPS system and nuclear power. Indirectly much of nano technology is based on special relativity so things like iPads, computers, modern cars, all have ingredients which can be...
Yes. Albert Einstein dropped out of high school at age 15.
This phenomenon occurs due to light's wave-like properties. Via diffraction, the bending of light wave about an obstacle, the light wave will interfere and exhibit dark and bright fringes on a screen as a result of this interference.
time shifting and space shifting are the acts of shifting time and space respectively, as in the sentence: "i have just shifted time and space".
Things such as Leaves on a tree even the rain even the sun in the sky these things of nature doesn't opperate by itself. These things were Created by The Creator and he alone make everything fall when it come's to nature.
first off its not weed its incense second off, online here its 3 grams for 30$
Normally its a lowercase c, as in E=m(c) 2 . Energy=mass times the speed of light squared.
According to Einstein's special theory of relativity, mass can be converted into energy, and is given by the relation E=mc2, where c is the velocity of light. From the question, the object thus will be converted into energy
Yes, time is affected by gravity. We know that the fabric of "reality" is spacetime, and spacetime can be warped by gravity. Gravity will thus affect time, as it cannot help but do so.
This is because no matter how large objects on earth may seem, they are nothing compared to the size things have to be to have significant pull on things. Objects would have to be many hundreds of miles across to get any sort of influence.
Answer quantum field theory, quantum electrodynamics, quantum chromodynamics, string theory . Energy is quantized
This was because he did not speak until later than most children, and learned other things much more slowly as well. And if you don't fix your spelling, people might think YOU'RE intellectually challenged...
Einstein was not an inventor, and did not invent anything.
The distinction is sometimes made to distinguish normal quantum mechanics (which does not incorporate special relativity) and quantum field theory (relativistic quantum mechanics). Since we know special relativity is correct it is the relativistic form of quantum mechanics which is true, but non...
He was born exactly 300 years after Galileo I'd kinda think that it more relates to the foundations that Galileo had been able to establish of which Albert Einstein was then able to form his theories
yes because it contains more gravitational potential as its mass has increased.
Many great articles on this subject exist.. Try: http://en.wikipedia.org/wiki/Mass-energy_equivalence
i assume you mean photon but I'm not 100% but "In physics, a photon is an elementary particle, the quantum of the electromagnetic interaction and the basic "unit" of light and all other forms of electromagnetic radiation. It is also the force carrier for the electromagnetic force . The...
what are the two forces acting immediately after leaving the launching pad of a rocket
A few examples: -UV radiation from the Sun stimulates the production of vitamin D in your skin. -UV radiation from black lights are used in the theater to make some objects glow. -UV radiation is used to check for fake money in shops. (Paper money usually has some kind of security feature...
An object is not accelerating when it is moving in a straight lineat an unchanging speed (which may be zero).
I hope I am not missing a joke. He needed it to navigate his sailing boat.
