near the sun, where the effect of gravity on time is greatest, what is the rate of precession - should be the greatest state the principle of equivalence - observations made in an accelerated reference frame are indistinguishable from observations made in a Newtonian gravitational field a circular disk with a clock in (clock 1) center, (clock 2) at edge, (clock 3) and on ground. - outer clock runs slower than inner clock. clock 1 & 3 run at same rate. clock 2 runs slower A measuring stick appears ________ to an observer who is not moving with the stick. (in an accelerated F.O.R. - contracted a piece of matter, even at rest and not interacting with anything else, has an "energy of being" this is called - rest energy a speck of matter with a mass of only 1 mg has a rest energy of - 90 billion J any accelerating object produces a gravitational wave. The more massive and object ----- - the greater its acceleration, the stronger the resulting gravitational wave applying principle of equivalence. (any effect of acceleration can be duplicated by gravity) we must conclude that as we move in the direction in which a gravitational force acts, time will be - slowed as the speed of an object approaches the speed of light, its momentum? - approaches infinity ball (thrown horizontal across spaceship) at a velocity equal to that of light - ball still curves downward (only to man inside observing) E=MC^2 is the ratio of - rest energy to massE=mc^2 what does C^2 mean - conversion factor between energy units and mass units. it converts the measurement of mass to the measurement of equivalent energy Energy and mass are - the same thing. if you want to know how much energy is in a system measure its mass gravitation is an interaction between masses . what is light - light may be massless but it is not energyless. therefore, gravity pulls on the energy of light because energy is equivalent to mass. how may observers in universe see us from their point of view - they see us living in slow motion hypothetical particles that could move both faster than light and backward in time are called - tachyons if the acceleration of the spaceship were equal to G the occupants could well be convinced that the ship - was not accelerating but was at rest on the surface of earth In a black hole, a photon, and frequency is - unable to escape-loses all energy. frequency gravitational red-shifted to zero in a rotating disk measurements of distance will depend on - strength of gravitational field in general relativity gravitational red shift depends on - one location of one point in a gravitational field relative to another one In our clock example, an observer at clock 3 sees clock 2 doing what - clock 2 runs slower because it is moving In our clock example, POV from observer at clock 1 sees clock 2 doing what - sees clock 2 running slowerin special relativity time dilation depends on the - speed of one frame of reference relative to another In triangles - lines of shortest distance are called - geodesic lines or geodisics measurements of time depend on both - relative motion and gravity photons of light are - massless A change in energy of any object at rest is accompanied by a change in - its mass since a photons frequency is proportional to its energy, its frequency - decreases as its energy decreases since every atom is a clock an a slowing down of atomic vibration indicates the slowing down of clocks. an atom on sun should emit light of a lower Frequency (slower vibration) than light emitted by the same element on earth. Since red light is at - lower frequency. lowering frequency shifts the color red. this is the gravitational red shift. The filament of a lightbulb energized with electricity has - more mass than when turned off. The ratio v^2 / c^2 is very small and for everyday speeds may be taken - to zero what does the concept of time apply to - events and entities within the universe, not the universe as a whole what does the path of a light beam follow - a geodisic
