Is the equation for displacement in the n th second dimensionally correct?

Is the equation for displacement in the n th second dimensionally correct? S = u + a (n- 1/2) Answer: Yes See the explanation given by Vimal Raj If we notice the derivation of this formula let t1=x and t2=y (for my easiness) S(y)=uy + 1/2 ay^2----------(1) S(x)=ux + 1/2 ax^2-----------(2) sub (2) from (1) S(y)-S(x)=uy … Continue reading Is the equation for displacement in the n th second dimensionally correct?
