Who created the “general theory of relativity”?
Albert Einstein
What does the “general theory of relativity” display? It reveals how ______ is related to _____ and ______
gravity, space, time
Einstein reasoned that space and period are two parts of a single whole called…
space-time
What does Einstein’s “special theory of relativity” describe? It describes just how ____ can be affected by _______ in space at a _______ velocity, and how ____ and ______ are related.
time, movement, constant, mass, energy
From the point of view of particular relativity, you travel through a variety of _____ and _____.
space, time
In case you stand continue to, are you journeying?
Yes, you are moving through time
In the event you move slightly, how are you vacationing?
some is through space and most of it is through time
If you push at the exceedingly fast, how are you vacationing?
all travelling is through space and non-e through time
Light journeys through space only and is also …
ageless
A photon traveling from one part of the universe to another, takes just how much time?
none of them (it travels at the rate of light)
How could you describe an individual’s travel from the viewpoint of special relativity?
space and time
What is a postulate?
assumption
What is time dilation?
the stretching of the time
In respect to unique relativity, mass and strength are …
equivalent
According to general relativity, gravity causes …
space to become bent and the perfect time to undergo changes
Precisely what is the speed limit in the universe for a subject with mass?
speed of light
What does “p=mv” stand for?
momentum equals mass times speed
What is p=(mv)/sqr(1-(v^2/c^2)), where v = speed associated with an object and c sama dengan speed of light
genuine momentum
As a subject approaches the speed of light, it is momentum…
boosts dramatically
When is Newton’s definition of impetus valid?
by low speeds
“Rest mass” of your object, represented by meters in the relativity equation, is actually a true regular, a property in the object whatever …
acceleration it has
How does an object’s energy change as it approaches the velocity of light?
That increases drastically.
For any particle which has a large impetus, the trajectory is …
stiffer
A piece of subject, even if sleeping and even in the event that not getting together with anything else, posseses an “energy of being” called its…
relax energy
What does E = mc^2 stand for?
Strength = Mass x (speed of light)^2
In E sama dengan mc^2, the speed of light, “c”, is a great quantity and its square is actually larger. Therefore a small amount of mass stores…
a great deal of energy
In Electronic = mc^2, the quantity c^2 is a “conversion factor. ” It changes the way of measuring of mass to the way of measuring of …
equivalent energy
For all those chemical reactions that give off strength, there is a corresponding…
decrease in mass
What is the relationship between mass and energy?
Mass and strength are the same.
The correspondence principle states…
that fresh theory and old need to overlap and agree in the region where the benefits of the older theory had been fully verified.
Based on the correspondence theory, if the equations of exceptional relativity (or any other new theory) are to be valid, they need to correspond to the ones from Newtonian mechanics when rates of speed are…
a lot less than the speed of light.
The equations of special relativity hold for all speeds, although they are significant only for speeds…
near the speed of light
The overall theory of relativity was a new theory of gravitation, in which the law of gravity caused space to become _______ and the perfect time to ____ _____.
curved, decrease
The principle of equivalence says that local observations produced in an more rapid frame of reference cannot be distinguished from…
observations produced in a Newtonian gravitational discipline
(There is no approach you can notify whether you are being pulled by gravity or perhaps being accelerated)
Arsenic intoxication mass produces a curvature or perhaps warping of …
space-time
A curvature of space-time shows the presence of
mass
The ripples that travel facing outward from the gravitational sources on the speed of light are…
gravitational surf
What is the relationship between the presence of mass plus the curvature of space-time?
mass produces the curvature of space-time
What is an illustration of how mass makes the curvity of space-time?
a ball resting on the waterbed
The first-person to understand the partnership between space and time was…
Albert Einstein
Light journeys through _____ only which is _______.
space timeless
What does the first postulate of special relativity state?
That states that every laws of nature are identical in all uniformly moving support frames of guide.
Einstein’s first �vidence of particular relativity assumes…
our inability to detect a state of uniform movement.
Einstein’s second postulate of unique relativity assumes…
that the exceedingly fast is continuous.
The 2nd postulate of special relativity states…
the fact that speed of light in empty space will always have similar value no matter the motion from the source or maybe the motion of the observer.
Time dilation occurs ever so slightly pertaining to ______ speeds, but substantially for speeds approaching __________
everyday, the speed of light
Does period dilation mean that time really passes slower in going systems or perhaps that it simply seems to move more slowly?
Period really does move more slowly within a moving program compared with one at relative rest.
If you were relocating a spaceship at a higher speed relative to Earth, would you notice an improvement in your pulse rate? Inside the pulse charge of the persons back on Earth?
No comparative speed between you and your heartbeat. There would be a relativistic result between you and people back that is known. You would locate their heartbeat rate slower and vice versa.
Distance/Time =
C or the speed of light
How does time dilation at day-to-day speeds match up against time dilation at light speed?
It is smaller in everyday speeds.
Will observers A and B agree on measurements of time if the moves at half the speed of light in accordance with B?
If a and B have different movements relative to one another, each will certainly observe a slowing of time in the framework of research of each various other. So , they will not agree on the measurements of time.
If the and B move with each other at zero. 5c relative to Earth, can they acknowledge measurements of the time?
Yes, they share similar frame of reference and may agree on measurements of time.
Time, as you may know it, journeys only one way –
ahead
Why does space travelling at relativistic speeds seem impossible?
The amounts of strength required to propel spaceships to relativistic rates of speed are billions of times the vitality used to position the space shuttles into orbit.
The observable shortening of things moving by speeds getting close the speed of sunshine is…
duration contraction
The amount of contraction is related to the amount of _____________.
period dilation
For ______ speeds, the number of contraction is significantly too small to be assessed.
everyday
As relative speed gets closer and closer to the velocity of light, the measured lengths of items contract deeper and better to…
actually zero.
A meterstick journeying at??? the speed of sunshine relative to a great observer can be measured as only ____ as long as typical.
half
Space contracts in only one direction, the direction of _____.
movement
A spacewoman moves by a circular planet and so fast it appears to her to be an ellipsoid (egg shaped). If she sees the brief diameter because half the long diameter, what is her speed in accordance with the planet?
87% of the speed of light
