Physics Solver by Photo: Get Step-by-Step Solutions From Any Problem Image

Physics problems are harder to type than math equations. A kinematics problem might have a diagram with labeled angles and initial velocities. A circuit problem has a schematic with resistors in series and parallel. A thermodynamics question might reference a P-V diagram. None of that translates cleanly into a text field.

Physics Solver by Photo takes the image directly. You photograph the problem exactly as it appears — diagram, labels, variables, and question together — and the AI reads everything in context. The solution that comes back is built from the complete problem, not a typed approximation of it.

Every solution includes the formula selected, the reason it applies, the substitution of known values, the calculation steps, and the final answer with correct units. This is the same structure a good physics teacher uses when working through a problem on the board — and it’s what actually helps you handle the next problem independently.

Which Physics Topics Does the Photo Solver Cover?

• Kinematics — displacement, velocity, acceleration, projectile motion, uniform and non-uniform motion, equations of motion
• Dynamics and Mechanics — Newton’s three laws, friction, tension, pulleys, circular motion, torque, momentum, conservation of energy and momentum
• Electricity and Circuits — Ohm’s law, series and parallel circuits, Kirchhoff’s laws, capacitors, resistors, power calculations
• Thermodynamics — heat transfer, specific heat capacity, ideal gas law, work done by gases, first and second laws of thermodynamics
• Waves and Optics — wave speed, frequency, wavelength, reflection, refraction, Snell’s law, lenses, mirrors, diffraction
• Magnetism and Electromagnetism — magnetic fields, Faraday’s law, electromagnetic induction, Lorentz force
• Modern Physics — photoelectric effect, de Broglie wavelength, atomic models, radioactive decay, nuclear reactions

How to Get the Best Results From a Physics Photo Solver

Include the full diagram in the frame

For physics problems with diagrams — free body diagrams, circuit schematics, ray diagrams — make sure the entire figure is in the photo, not just the text of the question. The AI reads the labeled diagram alongside the question to understand what values are given and what is being asked.

Tag the physics topic

Selecting the specific branch — Kinematics, Circuits, Thermodynamics — helps the solver apply the right framework from the start. A problem mentioning velocity could be kinematics (find displacement) or rotational mechanics (find angular momentum). The topic tag resolves this before processing begins.

Check the formula selected in Step 1

Physics solutions start by identifying the correct formula. Reading this step carefully tells you immediately whether the AI has interpreted the problem as you intended. If the formula matches what you’d choose, the rest of the solution will follow correctly. If it differs, that’s useful feedback about the problem’s ambiguity.

For multi-part problems, solve each part separately

Many physics problems have parts a, b, c where later parts use answers from earlier ones. Uploading each sub-question separately gives you a focused solution for each stage, with the specific formula and calculation path shown for that part alone.

Why Physics Problems Are Harder to Solve by Text Than Math Problems

A math problem is usually self-contained in its equation. A physics problem often has context that isn’t captured in the equation alone — a diagram showing the direction of a force, a circuit layout that determines whether resistors are in series or parallel, a graph of velocity vs. time that contains the information needed to find acceleration.

When you type a physics problem into a general text tool, you lose that context. You end up describing the diagram instead of showing it, and any description introduces ambiguity. Photo input removes that problem entirely. What’s on the page — equation, diagram, labels, and question — is what gets solved.

This is particularly important for circuit problems, where the topology of the circuit (which components connect where) is only visible in the schematic. And for optics problems, where the geometry of incident and refracted rays is what determines the answer. Text descriptions of these problems are always incomplete — the image is the problem.

Understanding Physics Step-by-Step: Why the Method Matters More Than the Answer

In most physics courses, the final numerical answer is worth a fraction of the total marks. The bulk of the credit goes to the working — selecting the correct formula, substituting values correctly, tracking units, and showing the logical path from given information to conclusion. A student who writes the right answer without the working often receives zero.

This is why a tool that shows only the answer is almost useless for physics. If you know a ball reaches 20.4 metres but don’t know that you used v² = v₀² − 2gh with v = 0 at the peak, you haven’t learned anything you can reproduce on the exam. Physics Solver by Photo is built around the principle that the method is the output — the final number is just where the method ends up.

Each solution structures the working the same way a good teacher or examiner would expect to see it: state the known variables, identify the relevant principle or formula, substitute values with units, perform the calculation step by step, and state the final answer with appropriate significant figures and units. This format is directly transferable to how you write up solutions in your own work.

Physics by Topic: What to Expect From Each Subject Area

Kinematics and Projectile Motion

Kinematics problems typically give you some combination of initial velocity, final velocity, acceleration, time, and displacement, and ask you to find the missing variable. The solver identifies which of the standard equations of motion (v = u + at, s = ut + ½at², v² = u² + 2as) applies based on what information is given and what is missing. For projectile motion, the horizontal and vertical components are handled separately, which is one of the most common points where students lose marks by mixing them together.

Newton’s Laws and Forces

Force problems usually require drawing a free body diagram first — showing all forces acting on an object — and then applying Newton’s second law (F = ma) to find acceleration or unknown forces. The solver reads force diagrams directly from the photo and identifies which forces are balanced and which produce net acceleration. Friction, tension in ropes, normal forces on inclined planes, and connected mass systems are all handled with the individual force components broken out clearly.

Electricity and Circuits

Circuit problems divide into two categories: simple Ohm’s law applications (V = IR) and more complex networks requiring Kirchhoff’s laws. For series and parallel circuits, the solver reads the circuit topology from the schematic and calculates equivalent resistance before applying Ohm’s law. For multi-loop circuits, Kirchhoff’s current law (sum of currents at a node = 0) and voltage law (sum of voltage drops around a loop = 0) are applied systematically. The solution shows which equation is used at each node and loop.

Energy and Momentum

Conservation problems are among the most reliable physics problem types because the method is consistent: identify the system, identify what is conserved (energy, momentum, or both), write the conservation equation, substitute known values, and solve. The solver makes the conservation principle explicit at Step 1 — stating which quantities are conserved and why — before proceeding to calculation. Elastic vs. inelastic collisions are identified from the problem description and handled with the appropriate equations.

Thermodynamics

Thermodynamics problems range from specific heat capacity calculations (Q = mcΔT) to ideal gas law applications (PV = nRT) to analysis of thermodynamic cycles. The solver identifies the type of process — isothermal, adiabatic, isobaric, isochoric — from the problem description and applies the appropriate version of the first law of thermodynamics. Heat engine efficiency and entropy change calculations are handled with the relevant formulas shown at each step.

Waves, Sound, and Optics

Wave problems typically involve the wave equation (v = fλ), the Doppler effect, or interference and diffraction. Optics problems use Snell’s law (n₁sinθ₁ = n₂sinθ₂) for refraction, the thin lens equation (1/f = 1/do + 1/di) for image formation, and the mirror equation for reflection. The solver reads ray diagrams and angle labels from the photo and applies the correct formula based on whether the problem involves a mirror, a lens, a boundary between two media, or a double slit setup.

Common Physics Mistakes the Step-by-Step Format Helps You Avoid

Forgetting to resolve vectors into components

Many physics problems involve forces or velocities at an angle. A force of 50 N at 30° to the horizontal has a horizontal component of 50cos30° and a vertical component of 50sin30°. Students often apply the full 50 N in one direction and get the wrong answer. The step-by-step output makes vector resolution explicit, showing the component breakdown before the force is used in any equation.

Mixing up which formula applies

Kinematics has five equations, each suited to a different set of known and unknown variables. Using v² = u² + 2as when you don’t know the displacement is a common error. The solver identifies which variables are given, which are unknown, and selects the equation that fits — making the selection logic visible so you can apply the same reasoning in future problems.

Dropping units mid-calculation

A student who writes “F = 5 × 3 = 15” has lost the units. If F is in Newtons, m in kilograms, and a in m/s², that needs to be tracked. The solver carries units through every calculation step, which also acts as a built-in check: if the units in the final answer don’t match what the question asks for, something went wrong in the working.

Using the wrong sign convention

In kinematics, taking “upward as positive” means gravitational acceleration is −9.8 m/s², and an object moving downward has negative velocity. In circuits, current direction and voltage polarity need consistent sign conventions for Kirchhoff’s laws to work. The solver states the sign convention used at the beginning of the solution and applies it consistently throughout, which is one of the most common sources of sign errors in student working.
