FAQs on Conservation of Momentum Video Lecture - Physics Class 11 - NEET

1. What is the principle of conservation of momentum?
Ans. The principle of conservation of momentum states that the total momentum of a closed system remains constant if no external forces act upon it. This means that the momentum before an event or interaction is equal to the momentum after the event or interaction.
2. How is momentum defined?
Ans. Momentum is defined as the product of an object's mass and its velocity. Mathematically, momentum (p) can be expressed as p = mv, where m is the mass of the object and v is its velocity.
3. Can momentum be transferred between objects?
Ans. Yes, momentum can be transferred between objects. When two objects interact, such as in a collision, the momentum of one object can be transferred to the other. This transfer of momentum occurs due to the principle of conservation of momentum.
4. What happens to the momentum of an object if its mass is doubled?
Ans. If the mass of an object is doubled while its velocity remains constant, its momentum will also double. This is because momentum is directly proportional to mass. Therefore, an increase in mass results in a proportional increase in momentum.
5. How does a collision affect the total momentum of a system?
Ans. In a collision, the total momentum of a system remains constant before and after the collision if no external forces are acting. This means that the sum of the momenta of the objects involved in the collision is the same before and after the collision.
