PHY 2053 Discussion Review: Chapter 1 1. Dimensional Analysis 1) Three fundamental dimensions:     2) Symbol used to express the dimension of quantity A:     Square bracket. [A] = dimension of A 3) Dimensions of velocity, acceleration and force:     [v] = [x]/[t] = LT -1 , [a] = [v]/[t] = LT -1 /T = LT -2  & [F] = [m][a] = M LT -2 4)  The dimensional analysis can be used to check correctness of an equation. How do  you use?        [A] = [B]   L l M m T n  = L p M q T r   5) The dimensions on the both sides of an equation agree. Is the equation correct?     Not necessarily. The dimensional analysis cannot determine dimensionless factors. 6) The dimensions on the both side of an equations does not agree. Is the equation
