In this module, you’ll begin your study of kinematics—the description of motion. You’ll learn how to represent motion using graphs and equations, and how velocity and acceleration describe how objects move and change speed over time. You’ll explore motion in a straight line and learn how to analyze relative motion between observers. These tools form the basis for understanding more complex motion in later modules.

This module extends your understanding of motion to two dimensions. You’ll explore projectile motion, including objects falling under gravity and moving through the air, and learn how horizontal and vertical motion combine. You’ll also study uniform circular motion, which describes the motion of planets, satellites, and many everyday systems. These concepts will help you analyze realistic motion beyond simple straight-line movement.

This module introduces Newton’s three laws of motion, which explain how forces affect motion. You’ll learn how forces cause acceleration, how motion depends on reference frames, and how forces always occur in pairs. These principles allow you to explain and predict motion in systems ranging from everyday objects to engineering structures and astronomical bodies.

In this module, you’ll explore important forces encountered in everyday life. You’ll learn the difference between mass and weight, and how gravity acts on objects. You’ll study elastic forces using Hooke’s law and examine contact forces such as normal force and friction. These concepts will help you understand how objects interact when pushed, pulled, stretched, or in contact with surfaces.

This module introduces the powerful concepts of work, energy, and power. You’ll learn how energy is transferred and transformed, and how energy conservation helps explain motion without directly calculating forces. You’ll explore kinetic and potential energy, conservative and non-conservative forces, and how power describes the rate at which work is done. These ideas connect physics to real-world applications, from human movement to machines and technology.

In this module, you’ll learn about momentum and how it helps explain collisions and interactions between objects. You’ll study impulse, conservation of momentum, and the difference between elastic and inelastic collisions. These principles allow physicists to analyze events ranging from sports and vehicle safety to particle physics and space exploration.

This final module explores gravity—the force that governs motion on Earth and throughout the universe. You’ll learn how gravity determines weight, orbits, and the motion of planets and satellites. You’ll explore gravitational potential energy, escape velocity, and how gravity shapes stars, galaxies, and black holes. This module connects the physics you’ve learned to the large-scale structure of the universe.
