Build intuition for motion, force, and Newton's laws, then choose the right tool for real dynamics problems
4 sections · 12 lessons
Define motion, force, coordinate systems, and acceleration so the language of mechanics is precise from the start.
3 lessonsDraw free body diagrams, identify net force, and apply Newton’s first, second, and third laws to straight-line dynamics and force pairs.
3 lessonsModel friction and drag, then compare force-based and energy-based approaches with work, kinetic energy, and conservation of mechanical energy.
3 lessonsExamine momentum and impulse in collisions, translate linear ideas to torque and rotational acceleration, and choose the right tool for motion problems.
3 lessonsForces and motion start with a simple question: what counts as a force, what counts as motion, and what does a physics model leave out? This course builds a grounded understanding of kinematics, Newton’s laws, friction, energy, momentum, and rotation so you can reason about straight-line and turning motion without relying on guesswork. It is designed for learners who want a clean mental model of mechanics from the ground up and a practical way to analyze problems with the right framework.
The course covers motion with position, time, speed, velocity, and acceleration, then moves into free body diagrams, net force, and Newton’s three laws. It also covers friction and drag, work and kinetic energy, potential energy and conservation, momentum and impulse, torque, and rotational Newton’s second law.
From project managers and operators to founders, analysts, and teams adopting AI, Fenzo is for people who want to get better at the work they already do.
Anything from using AI for project planning and analysis to improving workflows, decision-making, communication, and delivery. If you can describe the skill or task, Fenzo can build a course around it.
Yes. Tell Fenzo what you do, what you’re trying to accomplish, and where you’re stuck, and Fenzo will shape the course around your role, your goals, and the work you actually have to do.
No. Fenzo adapts to your starting point, so you can begin with the fundamentals or jump straight into more advanced work.
Yes. Fenzo for Business puts the whole team on one plan — shared seats, courses you can assign, and reporting on who has finished what.
See Fenzo for BusinessYou start by describing your goal or taking a short skill benchmark. Fenzo uses that context to identify gaps and shape the learning experience around them.

Something to operate in every section.
Three findings from decades of learning research shaped how every Fenzo lesson is built.

What the science says
Students in lecture-only classes are 1.5× more likely to fail.
How Fenzo does it
Every Fenzo lesson is interactive. No passive reading or watching, ever.
You work through itAI does it for you
Skill retention over time · with vs. without practice
What the science says
Offloading thinking to AI erodes the very skills you’re trying to build.
How Fenzo does it
Fenzo makes you do the thinking — guided, but never done for you.
Retrieval practiceRe-reading
Long-term recall · retrieval vs. re-reading
What the science says
Recalling information beats re-reading it for building durable understanding.
How Fenzo does it
Lessons weave in quizzes and recall prompts, so it sticks.
