check the dimension correct ness of E =1/2mv ^2 +mgh
Answers
Answer:
1/2mv² = mgh
we have to check the correctness
by dimensional analysis
So LHS
Dimensional formula of 1/2mv²
will. be [M¹ L²T-²]
so now RHS
mgh
dimensional 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 = RHS
it means formulas are dimensionally correct.
