Physics, brought
to life.
Welcome to my virtual physics lab. I’m Shamil Rathnayake, and I’ve brought together these interactive learning simulations for you, arranged around all 11 Sri Lankan G.C.E. A/L Physics syllabus units. Discover physics through hands-on exploration, right here on SR Physics.
Your virtual physics lab
Choose your Grade 12 or Grade 13 syllabus unit, then open a simulation. Use fullscreen for teaching, smart boards and projectors.
Forces and Motion: Basics
Unit 02 • Mechanics
Tip: Select a simulation on the left. Fullscreen enlarges the same embedded experiment; it does not take students to another website. Internet access is required to use these online simulations.

Shamil Rathnayake · SR PHYSICS
I’m Shamil Rathnayake, an electrical and electronic engineer and A/L Physics lecturer. My goal is to make difficult physics ideas simpler and more practical. I’ve organized this collection of interactive learning tools by Sri Lanka’s Grade 12 and Grade 13 Physics syllabus so you can explore, experiment, and build a clearer understanding of every lesson.
Whether you’re learning at home or using a smart board in class, I hope this space helps you see physics in action. Keep exploring — Next Gen Physics.
