The Story of Physics
Follow our guided path to understand the laws of the universe, from the motion of a falling apple to the fabric of spacetime.
Kinematics: The Science of Describing Motion
Our journey begins with the most fundamental question: How do things move? We'll learn to describe motion with precision using concepts like displacement, velocity, and acceleration.
The Ultimate Guide to Kinematics
This comprehensive guide covers displacement, velocity, acceleration, and free fall. Master the fundamentals of motion with interactive simulations and clear, step-by-step examples.
Forces and Newton's Laws (Dynamics)
We've learned how to describe motion. Now, we'll uncover *why* motion changes. This unit explores the concept of forces and Isaac Newton's three fundamental laws that form the bedrock of all classical mechanics.
The Ultimate Guide to Dynamics
This comprehensive guide covers forces, Newton's Three Laws of Motion (inertia, F=ma, action-reaction), and the resistive forces of friction and drag. Master the "why" behind motion with interactive simulations.
Work, Energy, and Power
Now that we understand forces, we can explore a new and powerful way to analyze motion: through the lens of energy. This unit introduces the concepts of work, kinetic energy, potential energy, and power.
The Ultimate Guide to Work, Energy, and Power
This comprehensive guide covers work, kinetic energy, potential energy, the law of conservation of energy, and power. Master a new way to analyze motion with interactive simulations.
