and does the n value keep changing

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.where they say you find the distance in 8th second or any other number
if they see find the distance in 8 seconds, so thats like from 0-8 seconds so you can use the normal s= ut + 1/2gt^2 and put t as 8
but if they say in a particular second then you should use the nth term formula
ohh
also for integration
yes
so the (2n-1) stays the same all the time right
it has come from deriving right, do yk the derivation
im not sure
the formula remains same, only the value of n you've to put
what does n represent here
so if you have difficulties in using this formula, when they talk about a particular second like lets say find the distance in 8th second, its the motion between 8th and 9th second so find the distance in 9th second and then find the distance in 8th second and subtract them, you'll get the same answer but thats lengthy so we use this formula
time
ohh okk
wait mb, 7th and 8th second
i understand
thanks a lot also in integration in the rhs is is it ALWAYS DT

Distance travelled in nth second Vs. Displacement in nth second (Cl...
The equation of motion that helps us find the displacement in the nth second of motion of a particle moving in a straight line is Sn = Vi + (2n-1) (a/2). However, students often make the mistake of incorrectly applying the formula to calculate distance travelled in the nth second. To avoid this confusion, it is essential to comprehend the fundam...
will watch it man thanks a lot
wdym?
i cant send pics here for some reaosn
its alr leave it if i face further problems imma send it here thanks once again
make another doubt thread and close this one :)
allr lemme figure out the problem and if i cant solve it imma ask you
