Physics · MOTION IN A STRAIGHT LINE
हिन्दीGiven below are two statements: Statement I: Sharp kinks in position-time or velocity-time graphs imply that acceleration changes infinitely abruptly at that instant. Statement II: In physical reality, velocities and accelerations cannot change instantaneously with infinite jumps. In the light of the above statements, choose the most appropriate answer from the options given below:
Correct answer · Option 1
Both Statement I and Statement II are correct.
Explanation
Sharp corners (kinks) in graphs represent non-differentiable points implying infinite rates of change, which are physically impossible for real macroscopic objects.
