How to Learn Physics Online for Free

Start with mechanics

Newton's laws, motion, and energy are the foundation of all physics. Our beginner courses walk through these concepts with real-world examples and interactive simulations.

Don't skip the math

Physics requires basic algebra and trigonometry. If those feel rusty, take our Mathematics beginner course first. The investment pays off when equations start making sense.

Visualize everything

Physics is about how the world works. Our courses use diagrams, simulations, and interactive widgets to show forces, waves, and fields in action — not just describe them.

Move to advanced topics

Once mechanics clicks, explore electromagnetism, thermodynamics, and quantum physics. Our intermediate and advanced courses build progressively.
