[edit] Intro - Motion, momentum, etc.
There were a few flaws in the introduction section.
- "motion is the result of applied force" is 99% correct, but it could be misunderstood as that sustained motion required sustained applied force (as was wrongly believed in ancient times). Basically, applied force results in change in motion. Linear motion is the result of absent (resulting) force).
- "Constant motion is the natural state of anything in the universe"?????? Give me a break! That's something you can tell your kids when they are 3. But it's just too wrong for an encyclopedia. Please don't believe everything that some kind of professor said... There is no notion of a "natural state" in physics. And most motion is definitely not constant!
- Laws in physics (or in any other science) are not responsible for anything, they do not cause anything. They are describe the nature. (Think about that!)

[edit] Removing ERIKA
hi, i'm removing some stuff is hard to make sense of in terms of modern physics, and i'm pasting it here in case someone can rescue it. Boud 15:50, 1 Jun 2005 (UTC)
- relative space and relative time result in relative motion, which means that the unit values of space and time can change for observers moving at high speeds relative to each other.
[edit] Kinds of motion
Italic text all kinds of motion are- 1.rotatory motion, 2.rectilinear motion, 3.translatory motion, 4.curvelinear motion, 5.oscilatory motion, 6.vibratory motion, 7.periodic motion, 8.non-periodic motion, 9.unoform motion, 10.non-uniform motion.
[edit] According to rate
1) uniform motion
2) (uniformly) accelerated motion 3) (uniformly) deceleretated

[edit] Motion defined by time = speed, yes?
I think we have the definition of motion wrong. If you put time into the definition, doesn't that become a measurement of speed? Hmmm?
Ye mi too (am JAZ 4rm Nig)no at all.
- I could argue otherwise. If time equals speed, then speed wouldn't neccessarily exist. You see, all of time, every impossibly small fraction of a second, contains an impossibly large amount of moments. To measure speed, you would need some kind of motion, even 0.0(repeating)1x10-99999(repeating) fm. However, an instant, a nothingth of a second, can have no movement. Therefore, even if multiplied infinitely, the 0 speed of an object in an instant would be 0. Now some would argue that 0 time has 0 speed, and x time would have y speed, so it isn't of any effect. However, if this moment in question doesn't matter, neither would any other. What would happen if you didn't have a single instant ever? There would be no time. There just isn't motion in a moment, so that means that if you don't have any of something in an increment, it wouldn't be in any larger incriments. By using time=speed, I could argue that motion is an illusion and all motion is stroboscopic. ChristopherEdwards 17:49, 5 October 2007 (UTC)
[edit] motion
There are four main types of motion.There's rotational, linear, reciprocating and also oscillating. —The preceding unsigned comment was added by 74.117.131.130 (talk) 22:15, 25 February 2007 (UTC).
