List of top Physics Questions on Pendulums asked in KEAM

For smaller angular displacement, the period of a simple pendulum depends on

Time periods of pendulums \( A \) and \( B \) are \( T \) and \( \frac{5T}{2} \). If they start executing S.H.M. at the same time from the mean position, the phase difference between them after the bigger pendulum has completed one oscillation is

If the period of a simple pendulum of length \(l\) is 5 seconds, then the period of the pendulum of length \(\frac{l}{4}\) is

In order to measure the period of a single pendulum using a stop clock, a student repeated the experiment for 10 times and noted down the time period for each experiment as $5.1, 5.0, 4.9, 4.9, 5.1, 5.0, 4.9, 5.1, 5.0, 4.9$ s. The correct way of expressing the result for the period is

The time period of a simple pendulum of length \( \sqrt{5} \) m suspended in a car moving with uniform acceleration of \( 5 \, \text{m s}^{-2} \) in a horizontal straight road is (\( g = 10 \, \text{m s}^{-2} \))

Two oscillating simple pendulums with time periods \(T\) and \(\frac{5T}{4}\) are in phase at a given time. They are again in phase after an elapse of time
