Investigating damped oscillations in simple pendulum

The Physical Educator, 2023
We describe an experimental set-up of a simple pendulum for the measurement of damping coefficient of oscillations. We have used an Arduino microcontroller with infrared sensor interface to detect the oscillating object in its path.

Limits of the simple pendulum formula for classroom use

The Physical Educator, 2022
We discuss the limits of the equation of the period of a simple pendulum, Ts=2πl/g , frequently used in high-school and university classrooms to measure the acceleration of gravity.

Renormalizing the Simple Pendulum

SIAM Review, 1993
Summary: The authors present an elementary scheme for calculating the period of oscillation or rotation of a simple pendulum. It is based on the invariance of the complete elliptic integral of the first kind under the arithmetic-geometric mean iteration.

Sound-based measurement of g using a door alarm and a smartphone: listening to the simple pendulum

The Physical Educator, 2020
Mainly, a door alarm system is used to measure gravitational acceleration. The magnetic switch component of the door alarm is turned on or off as the magnetic pendulum bob approaches or recedes from it.

Modeling damped oscillations of a simple pendulum due to magnetic braking

The Physical Educator, 2020
Using Tracker, a popular video-based physics modeling tool, the position-time data of magnetically damped oscillations of a simple pendulum are acquired. Eddy currents are generated on an aluminum sheet as the magnetic pendulum bob passes over it and the

Not-So-Simple Pendulums

Mathematics Magazine, 2021
Figure 1 shows the starting positions of two point masses on a pair of semi-elliptical tracks. Each track hangs vertically in a uniform gravitational field, and the masses are released simultaneous...

Approximate period for large-amplitude oscillations of a simple pendulum based on quintication of the restoring force

European journal of physics, 2019
A new approximate formula for estimating the period of the simple pendulum has been presented in this paper. The formula was derived based on ‘quintication’ of the restoring force of the pendulum, which replaces the original pendulum equation with an ...

The Simple Pendulum is not so Simple

SIAM Review, 1998
In this note it is shown that the equation of motion of a simple pendulum cannot be derived from Newton's laws of particle mechanics without hidden assumptions. The analysis of these assumptions leads to an interesting inverse problem.

Measurement of the gravitational acceleration using a simple pendulum apparatus, ultrasonic sensor, and Arduino

The Physical Educator, 2019
An insightful experimental procedure aimed to measure the gravitational acceleration is reported. The setup is made up of a simple pendulum apparatus, an ultrasonic position sensor, and an Arduino Uno board. The period of oscillations, which leads to the

Stability and Trajectories Analysis of a Fractional Generalization of Simple Pendulum Dynamic Equation

European Control Conference, 2019
In this paper, we present the dynamics of the simple pendulum by using the fractional-order derivatives. Equations of motion are proposed for cases without input and external forcing.
