A bullet fired from gun pierces a target due to:
Correct answer: C. Kinetic energy
- A. Mechanical energy
- B. Heat energy
- C. Kinetic energy
- D. Potential energy
Explanation
A bullet pierces a target because of its large kinetic energy, half mv squared, which comes from its very high speed. Its potential energy is unchanged along a level flight, and heat is produced by the impact rather than causing it.

About Kinetic Energy
Kinetic energy is the energy of motion, given for a nonrelativistic object by K = ½mv², so it depends on mass and the square of speed. Questions connect kinetic energy with work through the work energy theorem, calculate changes in kinetic energy, and distinguish it from momentum and potential energy.
