Why does a cannon recoil after firing ?
-
- Conservation of energy
- Backward thrust of gases produced
- Newton’s third law of motion
- Newton’s first law of motion
- Conservation of energy
Correct Option: C
Recoil is the backward momentum of a gun when it is discharged. In technical terms, the recoil caused by the gun exactly balances the forward momentum of the projectile and exhaust gases (ejecta), According to Newton's third law. In case of canons, the momentum is transferred to the ground through its mount.
