Question

As per your syllabus, if the MASS of an object doubles (while its speed stays the same), how does its KINETIC ENERGY change?

Accepted Answer

C. It DOUBLES (since KE ∝ m)

As per your syllabus, KE = ½mv².
Doubling m gives KE proportional to 2m — so KE doubles.
The other options misstate the dependence.

Answer

It stays the same

Answer

It becomes four times

Answer

It halves
