    NEWTON STATES:-

    An object remains in a state of rest or uniform motion in a straight line unless compelled to change that state by an applied force.

    I STATE:-

    An object remains in a state of rest unless compelled to change by an applied force.


    An object cannot remains in a state of uniform motion unless compelled to change by an applied force

    because
    Frictional force is there
    at any place where an object can be set in motion.So a force is required to balance the frictional force.

    Therefore a force has to be applied to keep a body moving with uniform motion, in the same state.
    For Eg:-
    A car moving with uniform motion if not accelerated for some time stops due to frictional force which is present everywhere and need not be applied

    MODERATOR NOTE : Adarsh Shankar, can you please refrain from using overly large and coloured fonts; for one thing it looks really childish, and also colours are generally reserved for moderator comments. Thank you.

    Tentatively moved to "New Hypothesis" for discussion.

    Friction is an "applied force", and therefore an object under the influence of friction will cease to move uniformly. Which is of course exactly what Newton's law says.
    You must understand that Newton's laws are one of the cornerstones of physics, and not something that can just be "disproved" like that. It is an empirical statement which we know to be true in its domain of applicability.

    I'm not allowed to use colors here? That's the most interesting part of this thread. Where's this rule written down?

    Which confirms Newton's first law. Well done.

    You can use colours to highlight words and sentences ( as you did above ), but we'd prefer people to not write their entire posts in colour, as the OP has done.

    Red to signify blushing induced by the embarrassment of this being on a science forum. Green for the nausea caused by the simple volume of threads like this that pop up.

    Is this rule written down somewhere? Please supply a reference. Else, how is it a rule?

    Oh yes, that's right: you did. Why did you do that?

    The original moderator statement was: " colours are generally reserved for moderator comments"

    As a relative newcomer here, I am asking for clarification. What does "generally reserved" mean? How would a newcomer to this forum know how much color is allowed and what color behavior will provoke the ire of a moderator?

    In this instance, it wasn't so much the use of colors, but rather the OP's use of large fonts in conjunction with physics crankery.

    This made my logical brain sit up and wonder whether the restrictions on the use of color are content based. In other words I can use all the color I want, as long as I'm stating conventional physics; but if I express unpopular views, I must post them in normal fonts and without the use of color.

    I am humbly seeking clarification on the moderator's comments regarding the OP's use of color and font.

    It's not a rule, you can use different size fonts and colors in your post. However, one of the first things they teach you in crackpot school is to make your posts in annoying colors and fonts, in order to cause maximum eye strain for your readers.

    I am humbly seeking clarification on the moderator's comments regarding the OP's use of color and font.

    If I had a new idea, that challenges an idea in e.g. modern physics, then how would I present it?

    I could opt for 2+2=4 approach. This is taking my audience by the hand because I know that they could (and should) be critical of my main conclusion. It is advisable to take them on a step-by-step track through the rationale, focusing on the logical progression of small sub-conclusions that will be accepted more readily than the final conclusion. Given the fact that any new idea (whether it seems valid or not) is given a skeptical look when it is introduced in a scientific discipline (e.g. physics), this is a good approach.

    I could also choose to stand on an electronic soap box, yelling that I have found a revolutionary theory that challenges mainstream physics.
    Instead of actually explaining the idea, I could hysterically point towards the physicists and yell "conspiracy!" ŕ la Alex Jones, whilst trying to sell DVDs and poorly written books.


    You can use color if you wish to stress some parts of your idea, but it is not recommendable to exaggerate with colors and fonts because it is not appealing. Just as reading someone's idea, expressed in a concise, coherent and calm manner is way more enjoyable than listening to the unsupported nonsense from the man on the soap box, although they both advocate for the same idea.
    "The only safe rule is to dispute only with those of your acquaintance of whom you know that they possess sufficient intelligence and self-respect not to advance absurdities; to appeal to reason and not to authority, and to listen to reason and yield to it; and, finally, to be willing to accept reason even from an opponent, and to be just enough to bear being proved to be in the wrong."

    ~ Arthur Schopenhauer, The Art of Being Right: 38 Ways to Win an Argument (1831), Stratagem XXXVIII.

    You know it because the moderator just told it to you. You did not provoke anyone's ire. It is not a written rule, just a practice that has become customary for the forum.

    It means just what I pointed out to you in my earlier post - you are welcome to use colours to highlight words and sentences in your posts ( for emphasise ), but you should not colour your entire post. The reasoning behind it is quite simple - there should be an easy way to visually distinguish a note/warning/comment made by a member of the moderator team, and on this particular forum this is done through colours. Normally green will be used for general moderator comments/notes, whereas red will be used for warnings and more decisive actions. If you have a look through some random threads you will see that this system is being consistently applied by all mods and admins.

    This isn't really a written-down rule as such, but a piece of forum etiquette; I also wish to clarify that this is an issue relating to form and layout, not content. I would have made the same comment to Albert Einstein himself, had it been him posting his ideas in the way the OP did.

    How would a newcomer to this forum know how much color is allowed and what color behavior will provoke the ire of a moderator?
    Excessive use of colour will be politely pointed out to him, as I did in this instance. There is no "ire" involved, I don't know where you get that idea; I know that he is a newcomer and hence probably not aware of this piece of etiquette.

    This made my logical brain sit up and wonder whether the restrictions on the use of color are content based.
    They are not.

    In other words I can use all the color I want, as long as I'm stating conventional physics; but if I express unpopular views, I must post them in normal fonts and without the use of color.
    No, that is not the case.

    It is one of those things known as an "unwritten rule". It falls under the same category as writing in all capital letters; it is considered poor netiquette, particularly when combined with an over-sized font. Not only that, but as pointed out above, it seems to be a style favored by crackpots. As such, you are risking that people will not read it, and dismiss the post based on that alone.

    Granted, the OP is young and thus might not be aware of this, but making an allowance for youth does not remove the need for correction.

    I believe it could also be called courtesy.

    It is difficult for people with eye issues, such as mine, to sometimes read certain colors against certain backgrounds.

    How would this apply to the movement of planets and galaxies, etc?
