AI Physics Solver

Work through a physics problem by choosing the model before substituting numbers. Mother can explain diagrams, assumptions, equations and units. Use it to understand why a method fits, not just to obtain a final number. Missing information should stay missing rather than become an invented measurement.

What to provide

Provide the full question, diagram labels, given quantities and required unknown. State your course level and what methods you have learned. Clarify whether distances are along a slope or vertical, whether friction matters and which direction is positive. If you have already tried a solution, paste your setup and ask Mother to find the first incorrect step.

Example starting request

A 2 kg block slides down a frictionless ramp inclined at 30 degrees. It starts from rest and travels 4 m along the ramp. Use g = 9.81 m/s². Draw the force diagram in words, choose axes, derive acceleration and find the final speed. Explain why mass cancels. Show units and cross-check the speed using energy conservation. Do not assume air resistance or add a coefficient of friction.

Worked example

Illustrative example, not a generated result or a user transcript.

Choose the positive axis down the ramp. The downhill component of weight is mg sin(30°), and the normal force balances the perpendicular component. Newton’s law gives a = g sin(30°) = 4.905 m/s². From rest over 4 m, v² = 2as = 39.24 m²/s², so v is approximately 6.26 m/s.

The mass cancels because both the downhill force and inertia are proportional to mass. As an independent check, the vertical drop is 2 m; equating the decrease in gravitational potential energy to kinetic energy gives the same speed. These numbers apply only to the stated frictionless model. Adding friction changes the force equation, while confusing ramp distance with vertical height changes the energy calculation.

Check the answer

Check units at every stage and test a limiting case: does acceleration vanish for a horizontal frictionless ramp? Compare a second method where possible, such as energy against kinematics. Confirm rounding and significant figures against your course rules. AI can make algebra or arithmetic mistakes; verify calculations independently. Use hints and your own explanation when the task is assessed, and follow your course policy. When calculation tools are enabled, Mother can evaluate bounded arithmetic expressions, not execute arbitrary code or act as a symbolic algebra solver. Ask for the expression and result, then verify the physical setup separately. For this ramp, sqrt(2 * 9.81 * sin(pi / 6) * 4) checks the speed; sin and cos use radians, so sin(30) is not the stated angle. If the answer disagrees, check angle units, the along-ramp distance and whether speed was confused with acceleration before changing the equation. A successful calculation cannot validate an incorrect model.
