Which of the following about an object performing simple harmonic motion is correct? Its acceleration
is maximum at the extreme ends
is constant and directed towards a fixed point
is zero when it is displayed from the equilibrum position
varies linearly with the displacement from a fixed point and is directed towards the fixed point
คำอธิบาย
In simple harmonic motion (SHM), the acceleration is maximum at the extreme points (maximum displacement) of the motion. These points are where the restoring force is strongest, leading to the highest acceleration. Therefore, the correct answer is 'is maximum at the extreme ends. although option D is also true.
