Final Answer:
The points indicating the amplitude of the Simple Harmonic Motion (SHM) in the given pendulum picture are a and c.
Step-by-step explanation:
In SHM, amplitude represents the maximum displacement from the equilibrium position. In a pendulum, the equilibrium position is when the bob is at its lowest point. As the pendulum swings, it reaches its highest points on either side. These highest points, labeled as points a and c, indicate the amplitude. Amplitude is the distance from the equilibrium position to the maximum displacement, and in this case, it corresponds to the highest points reached during the oscillation.
Understanding the amplitude is crucial in characterizing the extent of motion in SHM. It directly influences the energy and period of the oscillation. The amplitude is a key parameter used in the mathematical description of SHM, and it provides valuable information about the system's behavior.
By identifying points a and c as the positions where the pendulum reaches its maximum displacement, we can visualize and quantify the amplitude of the SHM. This comprehension aids in the analysis and prediction of the pendulum's motion and contributes to a broader understanding of harmonic motion principles.
