To find formulas and prove formulas... Say the formula for speed velocity=displacement/time v=s/t Displacement have the units of length thus itd dimensions are [L], time has the dimension of time [T] and the units for velocity is m/s which is meters per second..if analysed dimensionally we get [L]/[T] Thus dimensionally the equation is as follows: [L]/[T]=[L]/[T] Thus the formula is proven because both side of the equation is the same. anything, juz email me at hangmen_kipawz@Yahoo.com
