See It in Action
Turn a messy physics word problem into a clean, step-by-step solution with formulas, substitutions, and unit-correct final answers.
A car starts from rest and accelerates at 3 m/s^2 for 8 seconds. How far does it go?
Given: u = 0 m/s, a = 3.0 m/s², t = 8.0 s Find: s
Use kinematics: s = ut + (1/2)at² Substitute: s = (0)(8.0) + (1/2)(3.0)(8.0)² = 0 + 1.5 × 64 = 96 Unit check: (m/s²)·s² = m
Answer: s = 96 m

Pro Tips for Better Results
Get the most out of the AI Physics Solver with these expert tips.
Include units for every number
Physics errors often come from missing units. Add units (m, s, kg, N, J, V, Ω) to improve accuracy and ensure correct conversions.
State what you’re solving for
Add an “unknowns” line like “solve for acceleration and time” to keep the solution focused and avoid extra branches.
Describe directions and sign conventions
If directions matter (up/down, left/right, along incline), specify a positive direction. Clear sign conventions help with forces, acceleration, and electric fields.
Ask for a unit check when answers look wrong
If your result seems off by 10× or 1000×, it’s often a conversion issue. Keep unit checks enabled to catch dimensional mistakes early.
For multi-part problems, label each part (a), (b), (c)
If your problem has multiple questions, paste them as (a), (b), (c). The solver can answer each part with a consistent set of variables.

How to Use This AI Physics Solver (And Actually Learn From It)
Most “physics solvers” will spit out a number and call it a day. That is usually the worst part. Because in physics, the number is the easy bit. The hard part is picking the right model, setting up the equations, keeping your units consistent, and not getting tripped up by signs.
This AI Physics Solver is built for that middle part.
Here’s the simple workflow that tends to give the best results:
-
Paste the full problem statement
If there’s a diagram, translate it into text. Mention angles, directions, where forces act, what’s connected to what, and what’s “smooth” or “frictionless”. -
List your known values with units (optional, but honestly recommended)
Example:m = 2 kg, θ = 30°, s = 3 m, μ = 0.
This reduces guessing and makes unit conversions cleaner. -
Tell it what you want solved
“Find acceleration and time” is enough. If you leave it blank, it will infer it, which is fine. But explicit is better. -
Pick a solution mode
Use Step by Step when you want full working. Use Final Answer Only when you already know the method and just want to verify. -
Keep unit checks on
If you are off by 10x, 1000x, or a weird unit likem/swhen you expectedm, it is almost always a units issue.
What Types of Physics Problems It Solves Well
This tool is designed for common student style physics, including:
- Kinematics and Newton’s Laws: acceleration, forces, free body diagrams, incline planes, tension problems
- Work, energy, and power: conservation of energy, springs, friction work, power output
- Momentum and collisions: impulse, elastic vs inelastic, center of mass velocity
- Rotation: torque, angular acceleration, rolling without slipping, moment of inertia
- Gravitation: orbital speed, gravitational force, potential energy
- Fluids: pressure, buoyancy, continuity, Bernoulli (basic setups)
- Waves and optics: wave speed, frequency, refraction basics, lens equations
- Thermodynamics: ideal gas law, first law, basic heat transfer problems
- Electricity, magnetism, and circuits: Ohm’s law, equivalent resistance, power, electric fields, simple capacitors
If your question is messy or multi step, that’s fine. Just label parts like (a), (b), (c) so the output stays organized.
The Input Format That Gets the Best Step by Step Solutions
If you want the cleanest solution writeup, paste problems like this:
Problem:
A 2.0 kg block slides down a frictionless incline of angle 30°. Find its acceleration and the time to travel 3.0 m from rest.
Knowns:
m = 2.0 kg
θ = 30°
s = 3.0 m
μ = 0
u = 0 m/s
Solve for:
a, t
Even if you do not know the variables, you can write plain English. Like “time to reach the bottom” or “force in the rope”.
Common Mistakes This Solver Helps You Catch
Physics is full of tiny errors that ruin the final answer. A good step by step solution makes them obvious.
- Mixing degrees and radians (especially when trig shows up)
- Forgetting to resolve components on inclines:
mg sinθ,mg cosθ - Using the wrong kinematics equation for the knowns you actually have
- Sign errors when you pick a positive direction and then ignore it later
- Unit conversion slips like cm to m, minutes to seconds, kPa to Pa
- Rounding too early, then wondering why your final answer is off
If your output looks “reasonable” but doesn’t match a textbook answer, re run it with unit checks on and specify the sign convention. That usually fixes it.
Step by Step vs Final Answer Only (Which One Should You Pick?)
Step by Step is best when:
- you are learning the topic
- you need to show working for homework
- you want to see formula selection and substitutions
- you suspect a units issue
Final Answer Only is best when:
- you already solved it and want a quick check
- you are doing practice and want fast verification
- you only need the final numeric result with units
And if you are stuck mid solution, use the “Check My Work” mode and paste your attempt. That’s the closest thing to having someone point at the exact line where things went sideways.
A Quick Note on Studying With AI (So It Doesn’t Backfire)
Using AI to solve physics problems can be great for practice. But only if you treat it like feedback, not like a shortcut.
A good pattern is:
- Try the problem yourself first.
- Use the solver to compare steps.
- Identify the first place your solution diverged.
- Redo the problem once without help.
That last step matters more than people think.

Mini Example: Why Unit Checks Matter
Say you compute energy and end up with something like kg·m²/s². That looks ugly, but it is actually a joule. A unit check turns “ugly units” into confidence.
Same with:
N = kg·m/s²Pa = N/m²(m/s²)·s² = min kinematics
When your dimensional analysis works out, your chances of being correct go way up, even before you look at the final number.
When You Should Add More Detail to the Problem Statement
Add extra context when the problem includes:
- friction that changes (static vs kinetic)
- pulleys, multiple masses, or constraints
- electric fields with direction, sign, or geometry
- “at maximum height”, “just before impact”, “terminal velocity”, “steady state”
- anything with “assume no air resistance” or “assume small angles”
Basically, if a human teacher would ask a clarifying question, add that info up front. The solver can only use what you give it.
Summary
If you include units, state what you are solving for, and keep unit checks enabled, this AI Physics Solver will usually produce a clean solution that you can actually learn from. Not just a number. The whole path to the number.
