Question

The average acceleration in one time period in a
simple harmonic motion is
(a) A ⍵v (b) A ⍵²/2
(c) A⍵² / √2 (d) zero

Answer 1

Explanation:

The displacement in one cycle in SHM is zero, since particle returns to original position. Hence, average velocity and average acceleration both become zero.Option D is correct.

Answer 2

we know that acceleration is a vector quantity

and in simple harmonic motion the displacement of a particle is always zero and so the average velocity will be zero so this result in zero acceleration .
