- Kinetic energy is given by the formula KE = 1/2 mv2
- When two bodies are identical, they have the same mass.
- The kinetic energy depends on the square of the velocity.
- A higher velocity results in a higher K.E.
- Therefore, the body with a higher velocity has higher kinetic energy.
- Correct answer: B: Higher Kinetic Energy.

Understanding Kinetic Energy
Kinetic energy is the energy that an object possesses due to its motion. It is directly related to both the mass of the object and the square of its velocity. The formula for kinetic energy (KE) is given by:
KE = 1/2 mv²
Where:
- m = mass of the object
- v = velocity of the object
Key Concepts
- Identical Bodies: In this scenario, both bodies have the same mass (m).
- Higher Velocity: When comparing two identical bodies, the one with the higher velocity (v) will have a greater kinetic energy.
Impact of Velocity on Kinetic Energy
- Square of Velocity: Since kinetic energy is proportional to the square of velocity (v²), even a small increase in velocity leads to a significant increase in kinetic energy.
- Example: If one body is moving at 2 m/s and the other at 4 m/s, the kinetic energy will be:
- For 2 m/s: KE = 1/2 m (2)² = 2m
- For 4 m/s: KE = 1/2 m (4)² = 8m
- Conclusion: The body moving at 4 m/s has 4 times the kinetic energy of the body moving at 2 m/s.
Final Thoughts
Given that the body with a higher velocity has a quadratic relationship with its kinetic energy, it is clear that:
- Correct Answer: The body with a higher velocity has Higher Kinetic Energy.
This illustrates how motion and energy are intricately linked, emphasizing the importance of velocity in determining kinetic energy.
