Check the correctness of the equation 1/2mv^(2)=mgh, using dimensions. |
|
Answer» SOLUTION :The DIMENSIONAL formula of `1/2mv^(2)` is `M[LT^(-1)]^(2)=[ML^(2)T^(-2)]` and that of mgh is `[MLT^(-2)L]=[ML^(2)T^(-2)]` Each term on both SIDES of the EQUATION has the same dimensions. So the equation is dimensionallly correct. |
