FAQs on Problems on Linear Momentum Conservation

Question 1

1. What is linear momentum conservation?

Accepted Answer

Ans. Linear momentum conservation is a fundamental principle in physics that states that the total linear momentum of a closed system remains constant if no external forces act on it. This means that the sum of the momenta of all the objects in the system before an event is equal to the sum of the momenta after the event.

Question 2

2. How is linear momentum conserved in a collision?

Accepted Answer

Ans. In a collision, linear momentum is conserved if no external forces act on the system. This means that the sum of the momenta of the objects involved in the collision before the collision is equal to the sum of the momenta after the collision. The direction of the momenta may change, but the total magnitude of the momenta remains constant.

Question 3

3. What happens to linear momentum if an external force acts on a system?

Accepted Answer

Ans. If an external force acts on a system, the linear momentum of the system is no longer conserved. The momentum of the system will change in response to the external force. This change in momentum is given by the impulse-momentum principle, which states that the change in momentum of a system is equal to the impulse applied to it.

Question 4

4. Can linear momentum be conserved in an elastic collision?

Accepted Answer

Ans. Yes, linear momentum can be conserved in an elastic collision. In an elastic collision, both the total kinetic energy and the total linear momentum of the system are conserved. The objects involved in the collision bounce off each other without any loss of energy, and the total momentum before the collision is equal to the total momentum after the collision.

Question 5

5. Is linear momentum always conserved in a explosion?

Accepted Answer

Ans. No, linear momentum is not always conserved in an explosion. In an explosion, an object or system breaks apart into multiple pieces, resulting in an increase in the number of objects. In such cases, the total linear momentum before the explosion may not be equal to the total linear momentum after the explosion. However, the total momentum of the system can still be conserved if the external forces are negligible.
