SUMMARY
The equation l' = l + αa indicates that α is a dimensionless quantity of order unity, meaning it is approximately equal to 1. In practical terms, if l and a are known, α can be assigned a value close to 1, typically ranging between 1 and 3 for calculations. This understanding is crucial for accurately interpreting the relationship between l', l, and a in physics contexts.
