NEET Physics Gravitational Potential Energy MCQ Question
Which of the following statements about gravitational potential energy is correct?
Gravitational potential energy is defined as the work done in bringing a mass from infinity to a point in a gravitational field.
Gravitational potential energy can be negative and always increases as an object moves closer to the mass creating the gravitational field.
The gravitational potential energy is independent of the mass of the object being moved in the gravitational field.
The difference in gravitational potential energy between two points is not meaningful unless both points are compared to a common reference point.
Correct Answer
Detailed Explanation
Statement A is correct as it reflects the definition of gravitational potential energy mentioned in the NCERT content. Statement B is incorrect because gravitational potential energy decreases as an object moves closer to the mass. Statement C is incorrect since potential energy is proportional to the mass of the object. Statement D is misleading because the difference in potential energy can have meaning, but the zero point is conventionally set at infinity.
