Two simple pendulums of equal length cross each other at mean position. What is their phase difference ?
$180^{\circ}$ or $\pi \mathrm{rad}$
The period of a simple pendulum measured inside a stationary lift is found to be $T$. If the lift starts accelerating upwards with acceleration of $g/3,$ then the time period of the pendulum is
''Motion of simple pendulum from mean position for small displacement is a simple harmonic motion'' – Explain this statement.
Two simple pendulums whose lengths are $100 cm$ and $121 cm$ are suspended side by side. Their bobs are pulled together and then released. After how many minimum oscillations of the longer pendulum, will the two be in phase again
A heavy small-sized sphere is suspended by a string of length $l$. The sphere rotates uniformly in a horizontal circle with the string making an angle $\theta $ with the vertical. Then the time period of this conical pendulum is
What is linear harmonic oscillator ? And what is non-linear oscillator ?
