1/2 mv2 = mgh |
| Answer» Home>Check the equation 1 / 2 mvsquare=mgh is dimensionally correct or notQuestionCheck the equation 1/2mvsquare=mgh is dimensionally correct or notSolution1/2mv² = mghwe have to check the correctnessby dimensional analysisSo LHSDimensional formula of 1/2mv²will. be [M¹ L²T-²]so now RHSmghdimensional formula of mass is [M¹]dimensional formula of g (acceleration due to gravity) is [ L¹ T-²]dimensional formula of height(length) is [L¹]so dimensional formula of mgh will be= [M¹ L²T-² ]so LHS = RHSit means formulas are dimensionally correct. | |
