Concepts Of Physics MCQ Edition [Volume 1]PhysicsSimple Harmonic Motion
For a particle executing simple harmonic motion, what is the average acceleration over one complete time period?
Options
- Azero
- BA ^2
- CA ^2 2
- DA ^2 2
Correct answer
A. zero
Step-by-step solution
The acceleration of a particle executing simple harmonic motion is given by a = -A ^2 ( t + ) . The average acceleration over one complete time period T is calculated as the integral of acceleration over the time period divided by T . a = 1 T ₀^ T -A ^2 ( t + ) dt Since the integral of a sinusoidal function over one complete period is zero, the average acceleration is zero. Alternatively, average acceleration is defined as the change in velocity divided by the time taken. Over one complete time period, the particle
