Per NCERT, Galileo Galilei (1564–1642) was the FIRST to make quantitative studies of free fall. What specific result did he derive that is referenced in this chapter?
AForces equal mass times acceleration
BDistances in successive equal intervals follow the 1:3:5:7 ratio (the 'law of odd numbers')
CGravity varies with altitude
DE = mc²
Answer & Solution
Correct answer: B. Distances in successive equal intervals follow the 1:3:5:7 ratio (the 'law of odd numbers')
Per NCERT Example 2.5, Galileo derived the odd-number law for free-fall distances. F = ma is Newton.
