Solve Physics Problems Step by Step
Physics problems are word problems in disguise. The hard part is rarely the algebra: it is deciding which principle applies, which quantities you actually know, and which equation connects them. Solver AI's physics solver reads the problem from a photo and works through it step by step, starting from what the question gives you and what it asks for.
It covers the topics of high school physics, AP Physics 1 and 2, and intro college mechanics and electricity: kinematics and projectile motion, Newton's laws and free-body diagrams, friction and inclined planes, work, energy and power, momentum and collisions, circular motion, simple circuits with Ohm's law, and waves. Photograph a printed or handwritten question, or type it in.
Each solution explains why an equation fits, not only what it produces. For a projectile question you see the motion split into horizontal and vertical parts, the flight time found from the vertical motion, and that same time reused for the horizontal distance. If a step does not click, ask the AI tutor a follow-up by typing, by voice, or with another photo. Like any tool it can make mistakes, so follow the reasoning instead of copying the final line.
A handful of mistakes cause most wrong physics answers. Students mix units (centimeters with meters, grams with kilograms), drop the sign of a direction so a falling object ends up with a positive acceleration, use a constant-acceleration equation when the acceleration is changing, or forget that velocity and force are vectors that need components. Writing every quantity with its unit and choosing a positive direction at the start prevents most of them.
A dependable routine for any problem: sketch the situation, list the known values with units, name the unknown, then choose the principle (kinematics, Newton's second law, conservation of energy or conservation of momentum). Solve with symbols first and substitute numbers last, then check the answer's units and size. A car's stopping distance of 4,000 meters, or a ball thrown by hand staying in the air for ten minutes, is a sign to recheck a step.
Physics explains how phones charge, how bridges carry loads, how satellites stay in orbit and why seat belts save lives. The habits it trains (modeling a situation, tracking units, asking whether an answer is reasonable) are the same ones engineers and scientists use every day. Try each problem on your own first, then use the solver to check your answer or to find the exact step that went wrong.
Example problems
See how Solver AI breaks down problems step by step.
A car starts from rest and accelerates at 3.0 m/s² for 5.0 s. Find its final speed and the distance covered.
v = 0 + (3.0)(5.0) = 15 m/s; d = ½(3.0)(5.0)² = 37.5 m
A net force of 12 N acts on a 4.0 kg box. Find its acceleration.
a = F/m = 12 N ÷ 4.0 kg = 3.0 m/s²
A 9.0 V battery is connected across a 450 Ω resistor. Find the current.
I = V/R = 9.0 ÷ 450 = 0.020 A (20 mA)
A ball rolls off a 20 m high cliff at 5.0 m/s. How far from the base does it land? (g = 9.8 m/s²)
t = √(2 × 20 ÷ 9.8) = 2.02 s; x = 5.0 × 2.02 = 10.1 m
Frequently asked questions
What physics topics does Solver AI cover?
Kinematics and projectile motion, Newton's laws, friction and inclined planes, work, energy and power, momentum and collisions, circular motion, circuits with Ohm's law, and waves. That spans most of high school physics, AP Physics 1 and 2, and intro college mechanics.
Can I scan a physics word problem?
Yes. Snap a photo of a printed or handwritten physics question, word problems included, and Solver AI solves it step by step with the units written out. You can also type the question or ask the AI tutor about any step.
Does it explain which equation to use?
Yes. The steps say why an equation fits the situation, for example constant acceleration for the kinematics equations, or no outside forces for conservation of momentum, before any numbers are substituted.
Is the physics solver free?
Every user gets 3 free scans to try it. Unlimited use needs a Premium subscription, and prices vary by region.
