See why a thrown ball keeps moving forward while gravity bends its path into an arc

Define projectile motion as two simultaneous motions, and separate horizontal constancy from vertical acceleration.
3 lessonsCombine the two motion components into a curved trajectory, then relate launch angle to range, height, and flight time.
2 lessonsApply projectile ideas to sports and launches, and test the model against common myths and real-world limits.
1 lessonProjectile motion makes sense once horizontal motion and vertical motion are separated. This course builds that intuition from the ground up, showing why a projectile keeps a constant sideways speed while gravity changes its up-and-down motion just like it does for a dropped object. By the end, you can reason about curved trajectories, estimate range, height, and flight time, and spot where the ideal model stops matching real throws.
The course covers independent horizontal and vertical motion, constant horizontal velocity, constant downward acceleration from gravity, and the way those two motions combine into a parabolic path. It also covers launch angle effects on range, maximum height, and time of flight, plus real-world cases, air resistance limits, and common myths about falling objects.
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.

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.
