A rifle recoils when fired because
A.momentum is conserved for the rifle-bullet system
B.the bullet pushes the air
C.energy is conserved
D.gravity pulls the rifle back
Explanation
Core Concept
The bullet's forward momentum is balanced by the rifle's backward momentum.
Correct Answer
Amomentum is conserved for the rifle-bullet system
