Question
The following example follows the law of conservation of momentum. Is the statement true or false?
- true
- False
Hint:
- Law of conservation of momentum states that for two or more bodies in an isolated system acting upon each other, their total momentum remains constant unless an external force is applied.
The correct answer is: true
- Law of conservation of momentum states that for two or more bodies in an isolated system acting upon each other, their total momentum remains constant unless an external force is applied.
- Momentum is always conserved.
In the case of a gun the bullet leaves at high speed in one direction.
To conserve momentum the gun moves in the opposite direction. The gun is therefore held in such a position that it's recoil is controlled. Thus the gun and the person firing take the momentum.
