Core Topics Covered in Khan Academy Physics 1
The course is structured around essential physics concepts that form the backbone of classical mechanics. Here’s an overview of the main topics you’ll encounter:
Kinematics: Understanding Motion
Kinematics is the study of how objects move. Khan Academy Physics 1 starts here, covering:
- Displacement, velocity, and acceleration
- Graphical analysis of motion
- Equations of motion for constant acceleration
- Free fall and projectile motion
This section lays the groundwork for understanding how objects change position over time, a fundamental part of physics.
Dynamics: Forces and Newton’s Laws
Once you understand motion, the next logical step is to explore what causes it. Dynamics focuses on the forces acting on objects and includes:
- Newton’s three laws of motion
- Frictional forces
- Tension, normal force, and applied forces
- Free-body diagrams and force analysis
Khan Academy’s approach shines here by breaking down the sometimes abstract laws into relatable examples and practical problems.
Work, Energy, and Power
Energy concepts are critical for understanding how physical systems operate. This section explains:
- Work done by forces
- Kinetic and potential energy
- Conservation of energy principle
- Power and efficiency
These lessons highlight how energy is transferred and transformed, a key idea that connects many branches of physics.
Momentum and Collisions
Momentum offers another perspective on motion, especially in interactions between objects. Topics include:
- Linear momentum and impulse
- Conservation of momentum
- Elastic and inelastic collisions
Understanding momentum helps learners analyze complex situations like car crashes or particle interactions in a clear, mathematical way.
Rotational Motion and Gravitation
The course also covers rotational dynamics, a more advanced but fascinating topic, which includes:
- Angular velocity and acceleration
- Torque and rotational inertia
- Newton’s law of universal gravitation
- Orbits and planetary motion
These lessons prepare students to tackle real-world physics problems involving spinning objects and celestial bodies.
How to Make the Most of Khan Academy Physics 1

Create a Consistent Study Routine
Consistency is key when learning physics. Set aside regular time slots each week dedicated solely to video lessons and exercises. This steady pace helps reinforce concepts and prevents information overload.
Take Notes and Summarize Concepts
Even though the lessons are online, writing notes by hand or typing summaries can deepen your understanding. Try to paraphrase explanations in your own words and jot down key formulas or principles.
Practice Actively with Problems
Physics is best learned by doing. Don’t just watch videos passively—actively engage with the practice problems provided. Attempt extra problems from textbooks or online resources to challenge yourself further.
Use Visual Aids and Simulations
Khan Academy occasionally integrates animations and diagrams, but supplementing learning with external simulations (such as PhET Interactive Simulations) can provide a hands-on feel for abstract concepts like force vectors or energy transfer.
Don’t Hesitate to Review or Seek Help
If a topic feels confusing, revisit the videos or try different explanations elsewhere. Khan Academy’s community forums and other online physics communities can also be excellent places to ask questions and clarify doubts.
