Question

what is the difference between displacement in n seconds and nth second ??​

Answer 1

Answer:

Then, since the displacement covered in the nth second is nothing but the difference of the displacement covered in n seconds and that covered in n−1 seconds, we will subtract the displacement covered in n−1 seconds from the one covered in n seconds.

Answer 2

Explanation:

DISPLACEMENT IN N SECONDS : It refers to the shortest path covered by an object in n seconds of its motion.

DISPLACEMENT IN NTH SECOND : It refers to the path covered in a particular second of the total time taken for its motion between 2 places.

Displacement in nth second = u+[a/2 * ( 2n-1) ].
