NEET Physics Kinetic Energy Assertion Reason Question
Assertion (A): In a perfectly elastic collision, the total kinetic energy of the system is conserved. | Reason (R): During the collision of two objects, the velocities of both objects change in such a way that their relative velocity of approach equals their relative velocity of separation.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false, but R is true.
Correct Answer
Detailed Explanation
The NCERT context outlines that in an elastic collision, kinetic energy is conserved and the equation v1i - v2i = v2f - v1f supports the assertion by showing the velocities change to conserve kinetic energy.
