हिन्दीGiven below are two statements: Statement I: In every elastic collision, the kinetic energy of the colliding system remains constant at each and every instant during the collision process. Statement II: During the collision of two elastic bodies, the bodies deform and a part of the initial kinetic energy is stored temporarily as potential energy. In the light of the above statements, choose the most appropriate answer from the options given below:
Correct answer · Option 4
Statement I is incorrect but Statement II is correct.
Explanation
Statement I is incorrect because kinetic energy is not conserved at every instant during contact. Statement II is correct because deformation stores kinetic energy temporarily as elastic potential energy.
