To Check:
Correctness of the equation : v = u + at , by dimensional analysis.
Verification:
For an equation to be dimensionally correct, the dimensions of the LHS should be equal to the dimensions of the RHS.
LHS :
RHS :
Only quantities of similar dimensions can be added.
Similarly :
So , both LHS and RHS is same , hence the equation is dimensionally correct.
