Per NCERT, if the MASS of an object doubles (while its speed stays the same), how does its KINETIC ENERGY change?
AIt stays the same
BIt becomes four times
CIt DOUBLES (since KE ∝ m)
DIt halves
Answer & Solution
Correct answer: C. It DOUBLES (since KE ∝ m)
Per NCERT, KE = ½mv². Doubling m gives KE proportional to 2m — so KE doubles. The other options misstate the dependence.
