how can you relate the film "SPEED" to speed and velocity?
142545
speed and velocity are different things. velocity is a vector, i.e. it has a direction and value. speed is the value of such vector. In the movie they only keep the speed, not direction.

v stands for velocity, or how fast something is speeding up.\n\nfor example, if something is thrown at a velocity of 5ft/sec squared, its speed increases by 5 feet/sec every second it travels

You need to first figure out relative to what.  Relative to Gas, Relative to Plane?  Relative to inanimate person on the earth?  Velocity is also a Vector, so you need to define Speed and direction before you can figure this out.  So once you have the vectors for the Gas, Plane (relative to your point of relativity)  Just Add the vectors with your favorite vector adition method (in this case you will probably have 3 dimentional vectors)  Cheers

The first thing you have to understand is that the speed of light in a vaccum is constant, no matter how fast you're moving, nor how fast the source of the light is moving. This is bizarre. If someone standing on a conver tosses a ball to you at 5 mph while you're standing on the corner, you'll see the speed of the ball as being 5 mph relative to you. But if you're driving at 15 mph and they throw it at you at 5 mph, the speed of the ball relative to you will be 20 mph. This is how most things work. But with light, no matter the speed of the source or yourself, you'll always measure the speed of light as being 299,792,458 metres per second.\n\nEinstein accounted for this by postulating his special theory of relativity, which says basically that the reason for this is because if you move really fast, three things happen: 1) time slows down, 2) mass increases, and 3) length in directions parallel to the direction of movement contract. If you take those three hypotheses, you'll also note that the concept of things being "simulatanous" is a relative term, meaning two observers moving at the same velocity (or moving at no speed relative to one another) will agree on which events are simultaneous and which are not. However, observers at different velocities will have different concepts of what is and isn't simulataneous--and yet THEY'RE BOTH CORRECT. It's pretty mind-blowing, but if you take all of these notions together, you get a consistent view of reality.\n\nThat's Einstien's SPecial Theory of Relativity. About a decade later he formed his far more complicated general theory of relativity.\n\nThe general theory says that Newton's view that gravity operates by exerting a force on a falling object is incorrect. Rather, by general relativty, a free-falling object that is in a vacuum has no forces acting on it at all. The movement of falling objects isn't due to force, but rather the curvature of space-time--massive objects actually curve the surrounding universe. In Newtonian physics, we regard there being three spacial dimensions (up/down, left/right, and backwards/forwards) and a single dimension of time. In general relativity, there are four dimensions of space-time. In Newtonian physics, a foce makes the earth orbit around the sun. In general relativity, the earth and the sun curve the surrounding space-time continuum, and both bodies move in a straight line through curved space, resulting in the perceived sense that one body is circling about the other. In Newtonian physics, light should not bend to gravity, because gravity affects massive bodies, and light has no mass. But in fact, light does bend around stars and such.\n\nGeneral relativity has been likened to a stretched sheet of elastic material, like a trampoline. Heavier objects sink more, and make the sheet curve about them, and light obejcts rolling across are deflected by this curving.\n\nGood luck understanding all that. Hope your head doesn't explode.

Speed is distance/time.\n\nSo for examle if a car went 120 miles in an hour their speed would be 120 miles/per hour.

Very super question! Yes the answers above are right. Action-Reaction, sure enough. But you have asked what is totally QUESTION NUMBER ONE in physics. It's an exciting question which many teachers secretly don't understand and so their students get this hazy idea and kind of go thru the motions. Here's a way to remember and understand through a nutty story.\n\nWow, it is so basic, that it took a super-genius, I mean way smarter than Einstein, to figure it out. A good old farm boy, astrologer, magician & alchemist, religious fanatic, mathematician and all around kook. Yep. Sir Isaac Newton. You gotta wonder what kind of parents would name their kid "Sir"\n\nWell we all know what a force is, it is a sort of push or pull -- think of it as something that changes or *tries to change* the motion of stuff.\n\nNewton first figured out that if you leave a thing alone, or if the pushes and pulls on it cancel out, then it will sit there like a lump. Like those drivers wearing hats, and like sit there after the light has already turned green two minutes ago.\n\nOr else a thing will keep moving in the same straight line direction and speed like those drivers wearing hats who go 40 mph on the expressway with their turn signal blinking on and on. This is known as "THE HAT LAW".\n\nAll was well until he noticed that things move faster in an amount equal to how much you bully them or push them around. Twice the force, twice the fasterness and fasterness (also known as acceleration). This is called the "YOU BIG BULLY LAW".\n\nThen he discovered a fly in the ointment. His HAT and BULLY laws didn't really explain all that much. Something was gumming up this beautiful theory. We call it MASS and it is still an unknown mystery as to what it really is. So we vaguely call it the amount of stuff or matter in a thing.\n\nSo he found out that for a certain force the faster-isity (acceleration) is cut in half if you double the mass. The bully has to push twice as hard to fasterize two little kids. So he was like "I'll just add that in, and all will be cool". The "YOU BIG BULLY LAW" and "THE HAT LAW" totally did it all. Wa ta da babee!\n\nBut then Newton had a road accident. He was gunning his Harley over London bridge at like 250 when a bug hit him in the mouth and knocked out one of his wooden teeth. He was all "Why am I so in pain?". And the bug as it squooshed said "Help! I'm a bug!"\n\nSo spitting out the splinters of his wooden tooth and the splattered bug, he had this revelation. He realized that because he was moving so fast, and the bug slowed down so fast, that even a eentsy mass like a bug was like taking a hammer to his tooth.\n\nHe noticed that the force was equal to the mass of the bug times the speed of impact all happening in a brief moment. Since Newton spoke Latin (he was the love child of Joe Newton and an Italian governess) he wrote "Fastus buggus ina momentum hurtus like crazy." Today we call this "momentum". It is just "mass times speed" or "force times a small moment of time".\n\nAnd he realized that the bug smashed up his tooth, but also that the bug was squashed (like a bug) because they were trading the EXACT same amount of momentum. The force on the tooth by the bug in the moment of time was PRECISELY equal to the smacko-ing the tooth used to stop the bug dead.\n\nHe said "Hey, like he broke my tooth, but I killed him soooo dead!" He did the math and found that the force of the bug on the tooth was equal to the force of the tooth on the bug!\n\nNo way did the two equal forces cancel, after all, his tooth was hammered to splinters, and the bug was flattened. They were equal and opposite, but since one was on the tooth, and the other force was on the bug they did serious damage! Today we call this the "HELP I'M A BUG" law.\n\nNow our man 'Zack was all set. He wr

Speed.\nSpeed is only concerned with how fast your travel, and not with the direction.  (One example for velocity, by contrast, is that you drive 1000 miles east and then 1000 miles west in one day, but your velocity is zero, because you are at the same position, and the same reasoning can be applied to acceleration, as well as force).

speed is velocity - both measured as the change of distance divided by the change in time. You may mean the angular velocity, how fast is it spinning; or how fast the air is moving around the center (relative to the air not spinning); or how fast the tornado is moving across the ground.

Hannah-\nSpeed = Wave Length x Frequency\n(Manipulate that using rules of algebra to create a formula for W.L. and Freq.)\n\nRefraction of light is dependent upon the difference in the speed of light in the two media involved and upon the angle the light is entering (or, if you prefer, exiting).\n\nAngle of incedence = angle of reflection\n\nThere are a whole bunch of formuli for the specifics.  I don't know 'em - and, probably couldn't use them if they were given to me.  Good Luck

Instantaneous speed, as the name indicates, is measured at a particular instant of time. From a math standpoint, by calculating the first derivative of the displacement function, you can use the result to calculate the speed at any instant of time. In other words, the instantaneous slope of the displacement function is equal to the instantaneous speed.\n\nIf you look at graph of a moving object (displacement vs. time), if you see a steep slope, this means that the object's speed is fast relative to a curve with a moment of shallow slope. How much distance are you moving per unit of time? The more distance you move, the faster your speed. Decrease that unit of time to almost 0, and you'll get instantaneous speed.

The velocity of an object is simply its speed in a particular direction. Since velocity is defined as a vector, both speed and direction are required to define it.\n\n\nThe average velocity v of an object moving a distance d in a straight line during a time interval t is described by the formula:\n\n v=d/t\n\nPlease look at the below site for more details:\nhttp://en.wikipedia.org/wiki/Velocity

In the relativistic limit (i.e. speeds near the speed of light [here denoted "c"]) velocities are not additive in the normal sense.  In particular one must use the relativistic velocity addition rule given by:\n\nv_1 + v_2 / { 1 + (v_1 * v_2 / c^2 ) }\n\nWhere v_1 and v_2 are the speeds of the moving observers.  Notice that when v_1 and v_2 are both siginificantly less than c this reduces to \n\nv_1 + v2, which is what you expect from the everyday world.\n\nIf you plug in .95 c for v_1 and v_2 you obtain that the apparent velocity of the observers to each other is given by:\n\n.998685939553 c or 99.865% of the speed of light.\n\nWhich is how fast they will appear to approach each other from each other's perspective.

You have answered your question.\n Human eye can comprehend 10 images per second. More than that one cannot comprehend.\n\nTherfore, if film speed is 10 frames per second, every one can count the no of frames on seeing cinema. THE ILLUSION OF CONTINUITY will be lost and will only view a slideshow and not a motion picture.\n\nIf the flasing  rate is fast the flicker is not observed and the flashes appear continuous.\n\nIn earlier films , the speed used was 16 frames per second to obtain this illusion.\nIn these films one can perceive the lack of smoothness. \n\nThese effects are very much reduced  when 24 frames per second is used.\n\nIf we move a glowing match stick to and fro slowly we can follow the movement. If it is done fast  in a circular  motion we can perceive only a circle of light.

This is not related to relativity theory. It is relative velocity. If you are travelling in the same direction the speed at which the faster body moves, appears to be "speed of faster body - speed of you"\nWith bodies moving in opposite direction, this is "speed of faster body +speed of you"\nSee Velocity, Vector (Speed with direction) and Relative velocity.

This is a momentum question.\n\nMomentum = mass x speed\n\nSo, the original momentum is contained solely withing the moving engine and equals 4 units of mass times 5 km/h.  This equals a 'momentum' of 20.\n\nThe final momentum equals the combined mass of the engine and freight car, which is 4 units plus 1 unit for a total of 5 units of mass.\n\nSo, if Momentum = mass x speed, then since our final momentum is 20 (the same as the original momentum) and our final mass is 5, then 20 = 5 x Speed\n\nDividing both sides by 5 yields a final speed of 4 km/h.\n\nBest wishes and good luck.

Velocity is a vector quantity, meaning that it consists of both a magnitude AND direction component.\nFor two vectors to be equal, both their magnitudes and directions must be equal.\n\nFor two cars to habve the same velocity, their speed (the magnitude of their velocity) and the direction of travel must both be equal.
