Assertion : In a perfectly inelastic collision the kinetic energy is never conserved. Reason : The objects get deformed and stick together in perfectly inelastic collision.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.

For inelastic collision between two spherical rigid bodies:
1 The coefficient of restitution is equal to 1
2 The total kinetic energy is conserved
3 The linear momentum is conserved
4 The linear momentum is not conserved
Explanation:
In an inelastic collision, the particle do not regain their shape and size completely after collision. Some dfraction of mechanical energy is lost in the form of heat energy. Thus, the kinetic energy of particles is not conserved. However, in the absence of external forces, linear momentum is conserved.

Assertion : Two particles moving in the same direction do not lose all their energy in completely inelastic collision. Reason : Principle of conservation of momentum holds true for all kinds of collisions.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
If two particles are initially moving in the same direction, then their resultant momentum will not be zero. Therefore, their resultant momentum cannot be zero after a completely inelastic collision. As, kinetic energy is directly proportional to the square of the momentum, hence kinetic energy cannot be zero. This implies, not all the energy in inelastic collision is lost. So, both Assertion and Reason are correct and Reason is the correct explanation of Assertion.

Assertion : In an elastic collision of two bodies, only linear momentum (but not energy) of body is conserved. Reason : If two bodies stick to each other, after colliding, then the collision is said to be perfectly 'inelastic'.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
In an elastic collision, both momentum and kinetic energy are conserved. However, it's essential to note that this conservation principle applies to the system of bodies involved before and after the collision, not to individual bodies. Conversely, collisions where there is a loss of kinetic energy are termed inelastic collisions, which are common in everyday life. A perfectly inelastic collision occurs when two bodies stick together after the collision. So correct option is (4)
