Pendulum Simulation using Pygame

What is it?

• Simulation of pendulum
• Is a nice tech demo, in which gravity gradually increases, and you get to see the pendulum animate
• Features interactivity: user can modify pendulum's length

Usage

python ./pendulum.py

What I learned

• trigonometry in pygame using the math module
• basics of making a physics simulation
• converting math formulas and pseudo code from different language/library.
