+# <p align="center">Pendulum Calculator</p>
+
+## Description :-
+
+The Pendulum Calculator is a web application that calculates various properties of a pendulum system based on the length of the pendulum (l), the gravitational acceleration (g), the amplitude (A), and the mass of the bob (m). The calculator computes the following properties:
+
+- Period of the Pendulum (T)
+- Frequency of the Pendulum (f)
+- Angular Frequency (ω)
+- Maximum Speed
+- Maximum Acceleration
+- Kinetic Energy at the Lowest Point
+- Potential Energy at the Highest Point
+
+## Tech Stacks :-
+
+- HTML
+- CSS
+- JavaScript
+
+## Features :-
+
+- Calculate the period, frequency, angular frequency, maximum speed, maximum acceleration, kinetic energy, and potential energy of a pendulum system.
+- User-friendly interface with input fields for length, gravitational acceleration, amplitude, and mass.
+- Responsive design with a background image and enhanced styling.
+- Clear and detailed display of calculated results.
