AIIMS 2019 Physics Energy Conservation MCQ Question
The potential energy is converted into kinetic energy during sliding whereas in rolling; the some part of potential energy is converted kinetic energy, thereby decreases its kinetic energy of translation. Thus, velocity acquired by the body is less.
True
False
Cannot be determined
None of the above
Correct Answer
Detailed Explanation
In rolling motion, part of the potential energy (PE) is converted into both translational kinetic energy (KE) and rotational kinetic energy, which results in a lower translational velocity compared to sliding, where all potential energy is converted solely into translational kinetic energy. This distribution of energy in rolling leads to a decrease in the translational kinetic energy, making the velocity of the rolling object less than that of a sliding object under the same conditions. Option B is incorrect because the statement is true; option C is not applicable as the scenario is clear; option D is irrelevant as it does not address the question.
