Type: MCQ-conceptual-Easy-Class 11
Which of the following statements about mechanical energy in a system of particles is correct?
A
At maximum height, the energy is purely potential energy.
B
Kinetic energy is always greater than potential energy at all heights.
C
Mechanical energy is not conserved in the presence of conservative forces.
D
The total mechanical energy is the sum of kinetic and potential energy only at ground level.
Correct Answer
Option A
Detailed Explanation
At maximum height, the mechanical energy is entirely potential energy, as stated in the context where E_H = mgH indicates that energy is fully converted to potential energy at that point. Other options misrepresent the principles of conservation of mechanical energy.
