The Dimensional Balance
Every term in a correct physical equation reduces to the same combination of SI base units. Pick a candidate equation, weigh each side on the balance, and decide whether it is homogeneous. A balanced beam does not prove the equation is right, but an unbalanced one proves it wrong.
MissionChoose an equation, then predict balanced or not before you weigh it.Streak 0Best 0
Are the two sides dimensionally balanced?
left side in base units–
right side in base units–
Reduce every quantity to kg, m, s, A and compare. If the powers differ, the equation cannot be correct.
