Not another homework bot

Physics is something that happens.
You should get to watch it.

Most of the time, the thing standing between you and a physics problem isn't the concept. It's that you can't quite picture it: what's actually moving, when, relative to what. VisiPhysics exists to close that gap. Describe a problem, and it builds an interactive simulation of it, so you see it happen instead of just reading about it.

Why watching beats reading

Physics describes things that happen. Balls fall, cars collide, springs oscillate, and satellites orbit. These aren't just equations on a page. They're events we can visualize. VisiPhysics goes beyond just a written solution or a final number. It plays out the scenario, lets you adjust the different variables, and creates useful graphs. Of course, it also hands you the worked solution and explanation, once you've seen what you're solving for.

How it works

1
Describe or paste a problem in plain English.

Any objects, any forces, any setup. There's no fixed list of "supported" problem types (as long as the scenario can be simulated).

2
It's parsed into a real scene.

Every object's mass, position, velocity, acceleration, the forces that apply, and the actual worked-out answer… step by step.

3
A general physics engine runs it.

VisiPhysics generates your problem solution, simulation, and a range of useful graphs.

4
You explore it.

Play with the timeline, graph any quantity over time, adjust the values that actually matter, or ask a follow-up question about your specific problem to the AI Tutor.

Having taken two years of physics classes and tutored others along the way, I built VisiPhysics to address a problem my peers and I kept running into.

The more homework I worked through—and the more I helped classmates with theirs—the more I noticed the same pattern: the biggest struggle often wasn't understanding the physics concepts themselves, but visualizing the scenario described by the problem. What was actually moving? In which direction? Relative to what?

A paragraph of text can only go so far when the problem itself describes something happening in space and time. So, I built something that I hope can help!
