Question

Check the dimensional correctness of the following equations
mv 2 = mgh

b) v2 = u2 + 2 as​

Answer 1

Explanation:

mv2=mgh

mv2=>[M][LT-1]^2=[ML2T-2]

mgh=>[M][LT-2][L]=[ML2T-2]

THEY ARE DIMENSIONALLY CORRECT

v2=u2+2as

v2=[LT-1]^2=[L2T-2]

u2+2as=[L2T-2]+[LT-2][L]=[L2T-2]+[L2T-2]

THEY ARE ALSO DIMENSIONALLY CORRECT
