When a bullet is fired, the gun recoils backward. This recoil is best explained by
ANewton's first law of motion
BNewton's universal law of gravitation
CThe principle of moments
DNewton's third law of motion
Answer & Solution
Correct answer: D. Newton's third law of motion
1. The forward force on the bullet is the action force.
2. By Newton's third law, the bullet exerts an equal and opposite reaction on the gun.
3. This backward reaction force makes the gun recoil.
