Question

Statement I : Two particles moving in the same direction do not lose all their energy in a completely inelastic collision.Statement II : Principle of conservation of momentum holds true for all kinds of collisions.                                                                [AIEEE 2010]a)Statement I is true, Statement II is ture; Statement II is the correct explanation of Statement I.b)Statement I is true, Statement II is true; Statement II is not correct explanation of Statement I.c)Statement I is false, Statement II is true.d)Statement I is the true, Statement II is false.Correct answer is option 'A'. Can you explain this answer?

Answer

The strong interaction force between two bodies in which momentum is conserved is called collision. In any type of collision momentum is always conserved kinetic energy may or may not be conserved.

Answer

The strong intraction force between two bodies in which momenta is conserved is called collision.
in any type of collision momentum is always conserved kinetic energy may or may not me conserved.
so A is correct.

Answer

Statement I: Two particles moving in the same direction do not lose all their energy in a completely inelastic collision.
Statement II: Principle of conservation of momentum holds true for all kinds of collisions.

The correct answer is option 'A', which states that Statement I is true, Statement II is true, and Statement II is the correct explanation of Statement I.

Explanation:

Statement I: Two particles moving in the same direction do not lose all their energy in a completely inelastic collision.
In a completely inelastic collision, two particles stick together after the collision and move with a common velocity. In such a collision, the kinetic energy of the system is not conserved because some of the initial kinetic energy is converted into other forms of energy, such as heat or sound.

When two particles are moving in the same direction and collide inelastically, they do not lose all their energy because they have the same direction of motion. In this case, the final kinetic energy of the particles after the collision is lower than the initial kinetic energy, but it is not reduced to zero. This is because some energy is transferred between the particles, but they still have some residual kinetic energy due to their initial motion.

Statement II: Principle of conservation of momentum holds true for all kinds of collisions.
The principle of conservation of momentum states that the total momentum of a system of particles remains constant before and after a collision, provided no external forces act on the system. This principle holds true for all kinds of collisions, including elastic and inelastic collisions.

In an elastic collision, both momentum and kinetic energy are conserved. The total momentum before the collision is equal to the total momentum after the collision.

In an inelastic collision, only momentum is conserved, while kinetic energy is not conserved. However, the principle of conservation of momentum still holds true, meaning that the total momentum of the system is conserved.

Explanation of the answer:
The answer is option 'A' because both Statement I and Statement II are true, and Statement II provides the correct explanation for Statement I.

In a completely inelastic collision between two particles moving in the same direction, some energy is transferred between the particles, but they still retain some residual kinetic energy due to their initial motion. This is why Statement I is true.

Statement II is also true because the principle of conservation of momentum holds true for all kinds of collisions. In an inelastic collision, the total momentum of the system is conserved, even though the kinetic energy is not conserved. This is why Statement II is the correct explanation for Statement I.
