which of the following statements about simple harmonic motion is correct? The
-
total mechanical energy is always conserved
- linear acceleration is directed to any variable point
- linear acceleration varies inversely with displacement
- period of oscillation varies linearly as acceleration due to gravity
The correct answer is: A
Explanation
In SHM, the total mechanical energy (the sum of potential and kinetic energy) remains constant, provided no damping or external forces are acting on the system.
