MCQ
The average acceleration in one time period in a simple harmonic motion is:
- A$\text{A}\omega^2$
- B$\frac{\text{A}\omega^2}{2}$
- C$\frac{\text{A}\omega^2}{\sqrt{2}}$
- ✓$\text{Zero}.$
✓
Answer
Correct option: D.
$\text{Zero}.$
The acceleration changes its direction (to opposite direction) after every half oscillation. Thus, net acceleration is given as,
$\text{A}\omega^2+(-\text{A}\omega^2)=0$
$\text{A}\omega^2+(-\text{A}\omega^2)=0$
