SUMMARY

The energy of a bullet fired from a gun and a rifle with the same linear velocity is fundamentally equal, calculated using the formula E = ½·m·v², where 'm' is mass and 'v' is velocity. However, a rifle bullet possesses slightly more energy due to additional rotational energy. The increased accuracy and distance of rifle bullets are attributed to reduced tumbling and air resistance, not solely energy differences.

PREREQUISITES
  • Understanding of kinetic energy principles
  • Familiarity with bullet dynamics
  • Knowledge of rotational energy concepts
  • Basic physics of projectile motion
NEXT STEPS
  • Research the effects of rotational energy on projectile performance
  • Explore the physics of air resistance in bullet trajectories
  • Study the differences in bullet design between rifles and handguns
  • Learn about the impact of velocity on bullet accuracy and distance
USEFUL FOR

Ballistics experts, firearms enthusiasts, and physics students interested in the dynamics of projectile motion and energy transfer in firearms.

How we differentiate the amount of Energy of a bullet fired by a gun and a rifle with same linear velocity?

do they posses the same energy ? or rifle has more energy than gun.
 
Physics news on Phys.org
The energy of the bullet would be E = ½·m·v²

So for the same m and v the energy would be equal, regardless of how the bullet was fired.

the rifle bullet will have very slightly more energy, since it will also have rotational energy

it travels further (and is more accurate) not because of its energy, but because it tumbles less than the gun bullet, and so has less air resistance :wink:
