Type: MCQ-conceptual-Easy-Class 11
Which of the following statements about mechanical energy in a system of particles is correct?
A
The total mechanical energy is conserved in the absence of non-conservative forces.
B
Kinetic energy can be fully converted to potential energy without any loss.
C
Mechanical energy can be increased by applying a non-conservative force.
D
At the highest point of motion, the energy is entirely kinetic.
Correct Answer
Option A
Detailed Explanation
The total mechanical energy is conserved when only conservative forces are acting, as illustrated by the conversions between kinetic and potential energy in a system, with no mention of non-conservative forces causing energy loss.
