If the linear momentum of a moving object gets doubled due to application of a force, then its kinetic energy will
General KnowledgePhysics
- Aremain same
- Bincrease by four times
- Cincrease by two times
- Dincrease by eight times
Explanation
Kinetic energy equals p-squared divided by 2m, where p is linear momentum. If the momentum doubles, the kinetic energy becomes (2p)-squared over 2m — that is, four times the original kinetic energy. The correct answer is four times.
