Is this expression dimentionally consistant? [tex]v^2=2ax[/tex] where v is velocity, a is acceleration and x represents a length in meters. [tex](m/s)^2=2*m/s^2 * m[/tex] [tex]m^2/s^2=2*m/s^2 * m[/tex] [tex]m^2/s^2 = 2 * m^2/s^2[/tex] I'm not sure if the 2 makes the thing not dimentionally consistant. My guess is since the 2 is unitless, the expression is dimentionally consistant. Any thoughts?
