Question

Which of the following statements describing simple harmonic motion of a block-spring system
is NOT correct: (see picture attached). What is the correct answer, and why is it correct? 

### Fundamental Principles of Harmonic Motion

A. **Total Energy Conservation:**
   \[
   E = \frac{1}{2}kA^2
   \]
   This formula represents the total energy \(E\) in a system where \(k\) is the spring constant and \(A\) is the amplitude. This implies that the total energy remains constant throughout the motion.

B. **Hooke's Law:**
   \[
   F = -kx
   \]
   This equation describes the force \(F\) applied to a spring in terms of its displacement \(x\), where \(k\) is the spring constant. It indicates that the force is proportional and opposite to the displacement, following Hooke's Law.

C. **Angular Frequency:**
   \[
   \omega = \sqrt{\frac{k}{m}}
   \]
   Here, the angular frequency \(\omega\) is determined by the spring constant \(k\) and mass \(m\). This relationship shows how the angular frequency depends on these parameters.

D. **Period and Frequency:**
   \[
   T = \frac{1}{f}
   \]
   The period \(T\) is inversely related to the frequency \(f\), implying that the period is directly proportional to the inverse of the frequency, governed by the formula. Here, \(T = 2\pi f\) is incorrect in reality.

These equations and principles are essential in understanding the dynamics of simple harmonic motion in physics.
