Question

The law of motion involved in the recoil of gun is: ____.

• A. Newton's first law of motion
• B. Newton's second law of motion
• C. Newton's third law of motion
• D. none of these

Hint:

Action and reaction forces always act on different bodies. In this case, the action is on the bullet, and the reaction is on the gun. This is why they don't cancel each other out!

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Recoil is the backward movement of a firearm when it is discharged. This is a direct physical result of forces acting in opposite directions between two interacting bodies.

Step 2: Detailed Explanation:
According to Newton's Third Law of Motion, "To every action, there is always an equal and opposite reaction." When a bullet is fired from a gun, the force pushing the bullet forward is the "action." Simultaneously, the bullet exerts an equal and opposite force on the gun, pushing it backward. This backward force is the "reaction," which causes the gun to recoil. This event also demonstrates the conservation of momentum, as the total momentum of the system remains zero before and after firing.

Step 3: Final Answer:
The law involved in the recoil of a gun is Newton's third law of motion.
