Example 2.15 Let us consider an equationmu-=mgh2where m is the mass of the body, u itsvelocity, g is the acceleration due togravity and h is the height. Checkwhether this equation is dimensionallycorrect.

Answer»

M is on both side so its dimension is matchedV^2 have dimension m^2/s^2And g*h have m*m/s^2 = m^2/s^2.So the dimension is matched
