The law of conservation of linear momentum applies to a system when:
A
Mass is constant only
B
External force is maximum
C
External force is zero
D
Internal forces are zero
Correct Answer: Option C — External force is zero
Explanation:
Linear momentum of a system is conserved when the net external force acting on it is zero, meaning the total momentum before an event, such ...
Linear momentum of a system is conserved when the net external force acting on it is zero, meaning the total momentum before an event, such as a collision, equals the total momentum after it.
