# The phase difference between displacement and acceleration of a particle in a simple harmonic motion is: Option: 1 Option: 2 Option: 3 Option: 4 zero

Answers (1)

\begin{aligned} &\text { SHM is represented by }\ displacement= \mathrm{x}=\mathrm{A} \sin \omega \mathrm{t}\\ &\text { Then, the velocity and acceleration after differentiation will be }\\ &\mathbf{v}=\mathbf{A} \omega \cos \omega \mathbf{t}\\ &\mathrm{a}=-\mathrm{A} \omega^{2} \sin \omega \mathrm{t}=\mathrm{A} \omega^{2} \sin (\omega \mathrm{t}+\pi) \end{aligned}

So the phase difference between x & a= $\mathrm{\pi \ rad}$
