What happens to the linear momentum of a moving object if its kinetic energy is doubled, assuming its mass remains constant?
A. It doubles
B. It increases by a factor of four
C. It increases by a factor of the square root of two✓ Correct Answer
D. It remains unchanged
💡 Solution & Explanation
Kinetic energy is related to linear momentum through the mathematical expression where kinetic energy equals the square of momentum divided by twice the mass. Consequently, momentum is proportional to the square root of kinetic energy, meaning a doubling of kinetic energy increases momentum by a factor of the square root of two. Conceptual physics problems involving motion and energy are common in competitive tests.
