Q. If both the mass and the velocity of a body is increased to twice of their magnitude, the kinetic energy will increase by
✅ Correct Answer: (C)
8 times
Explanation: If you double mass and double velocity, you get eight times the kinetic energy, no matter what your first energy is. As an object's kinetic energy increases, and momentum is mass x velocity.
