\[S= ut +\frac{ 1 }{ 2 }a t^2\] use this and you are done , put t= n and t= n1
 one year ago

jasonxxBest ResponseYou've already chosen the best response.2
there will be two equations
 one year ago

mathsloverBest ResponseYou've already chosen the best response.0
right and we get : \[\large{S_n = u + \frac{a(2n1)}{2}}\]
 one year ago

mathsloverBest ResponseYou've already chosen the best response.0
but can we prove that : \[S_n  S_{n1}=S_n\] ?
 one year ago

jasonxxBest ResponseYou've already chosen the best response.2
No because \[S _{n}\] is the distance traveled in nth second and S(n1) is the distance traveled in (n1) seconds, how could their difference be equal to distance traveled in n seconds ... think :)

mathsloverBest ResponseYou've already chosen the best response.0
yes very correct but the formula says S_n = u + a(2n1)/2
 one year ago

mathsloverBest ResponseYou've already chosen the best response.0
Oh! OK, so it is S_nth = u + a(2n1)/2 ?

@mahmit2012 it's physics i guess

s= displacement, sorry for telling later.

@mathslover shall i derive the whole equation?
 one year ago

mathsloverBest ResponseYou've already chosen the best response.0
no no I had done that
 one year ago

mahmit2012Best ResponseYou've already chosen the best response.2
it is no different.
 one year ago

jasonxxBest ResponseYou've already chosen the best response.2
okay then where are you stuck?
 one year ago

mathsloverBest ResponseYou've already chosen the best response.0
just confirm me that : \[\large{S_{n^{th}}= u + \frac{a(2n1)}{2}}\]
 one year ago

mahmit2012Best ResponseYou've already chosen the best response.2
for all sequences you can use that.

mathsloverBest ResponseYou've already chosen the best response.0
@mahmit2012 how can s_n = a _1 + .... + a_n? I hope you are taking s = displacement and a = acceleration and n = seconds
 one year ago

mahmit2012Best ResponseYou've already chosen the best response.2
so if Sn is meant the nth distance for a traveling with constant acceleration you can use it.

mathsloverBest ResponseYou've already chosen the best response.0
Oh, k thanks @jasonxx I was just confused with nth and n seconds. :) Well, now I am interested to learn something new from mahmit2012. I am sure he has a good reaso for his solution

mathsloverBest ResponseYou've already chosen the best response.0
Any example or more explanation @mahmit2012 ?Please?
 one year ago

jasonxxBest ResponseYou've already chosen the best response.2
@mahmit2012 for all sequence but does it look like that this formula makes a proper sequence ? if a body is accelerated it won't be covering equal distance under under different time interval, still if you think you're right i would love to see that ...and @mathslover you're welcome

can distance vary according to a sinusoidial function ??
 one year ago

mahmit2012Best ResponseYou've already chosen the best response.2
and so on...you can have many answer for all motions.

jasonxxBest ResponseYou've already chosen the best response.2
can distance vary as per the sine rule ? if yes can you give an example i'll be very thankful

@mahmit2012 i'll try my best to understand your explanation but i am not sure how the function of distance is in the form of sine, which is traveling on a straight line ..thank you
 one year ago

jasonxxBest ResponseYou've already chosen the best response.2
and what you've done is just a differentiation of S= A sin wt twice

@mahmit2012 brother i just need an example of the motion, a real life example and i don't think we need to bring fourier series whilst dealing with kinematics
 one year ago

mahmit2012Best ResponseYou've already chosen the best response.2
All motions are related with Forier series. In one dimension or more.

concept of fourier series looks good whilst dealing with electric current and voltage, i am sure and i agree you have a good point
 one year ago

mahmit2012Best ResponseYou've already chosen the best response.2
this is the simplest motion and has just one w. for all motions you can have infinity frequencies.

@demitris do you agree what @mahmit2012 has said? i'll be thankful if you could help to know further

No worries, I will catch this with a helicopter soon :) This all is going over my head but still helicopter will catch it for sure ;)

well it says, what is the value of the difference of the distance traveled by a body in n seconds and n1 seconds in context of classical mechanics
 one year ago

jasonxxBest ResponseYou've already chosen the best response.2
@demitris i think if i'll keep you providing conditions i am sure it will take way too long and yes u is initial velocity, have mercy please :)

@demitris that has already been done thanks for your work tho
 one year ago

jasonxxBest ResponseYou've already chosen the best response.2
yes ..but the logic provided by 2mahmit2012 was having some fallacy i asked you to check that out ..but thanks for your concern
