NEET Physics (general) MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Which of the following combinations about the conservation of mechanical energy is correct?
A
At height H, energy is purely potential; at height h, it's partially kinetic and potential; at ground level, it's fully kinetic.
B
Mechanical energy is only conserved when forces are constant.
C
Work done by conservative forces always increases kinetic energy.
D
Potential energy is maximum at ground level.
Correct Answer
Option A
Detailed Explanation
The correct statements reflect the conservation of mechanical energy, where energy transformations occur between potential and kinetic forms at different heights, specifically noted in the context of gravitational potential energy.
