The recoiling of gun is an example of which of the following?
A. Law of Conservation of Angular Momentum
B. Law of Conservation of Linear Momentum
C. Conversion of Kinetic Energy to Potential Energy
D. Law of Conservation of Energy
Answer: Option B
Solution(By Examveda Team)
The recoiling of gun is an example of Law of Conservation of Linear Momentum. When gun fires a bullet, it experiences a force in forward direction (action) , as a result the gun exerts a backward force (reaction) on the shoulder.This Question Belongs to General Knowledge >> Physics
