☜☆☞ It depends on how velocity is changed.
1)- If velocity is kept constant then with double the mass kinetic engery will also double.
2)- if momentum is kept constant and mass is doubled then kinetic energy will become half.
( an object of mass m is moving with velocity 'v’ if another object of same mass is gently placed on it—- momentum kept constant ).
