MechanicsMania

Founded by for the purpose of advancing and easing physics knowledge.

A workbench for calculus-based mechanics. Solve the problem, watch the scenario run, then read back the derivation.

STEP 01

Choose the physics

Sixteen chapters, opening with the multi-concept scenarios that recur on the exam and working back through the ideas they are built from.

STEP 02

Enter what you know

Answer a short sequence of questions. Leave anything you weren't given blank — the solver works around the gaps.

STEP 03

See it, then follow it

The scenario animates alongside the answer, and the derivation unfolds step by step as you scroll.

Contents

What are you working on?

Each chapter solves for any quantity you're missing, given whatever else you know.

Picking the right setup narrows down which quantities matter.

Before you start

Key

Setting up

What are you solving for?

Choose the unknown. Everything else becomes an input.

Press Enter to continue. Skip anything the problem didn't give you.

Net force

List every force acting on the object

Use negative values for forces pointing against your chosen positive direction.

ΣF = 0.00 N

Plot the data

Pick any two recorded quantities. Choose a transform to straighten a curve, and the slope of the resulting line is the constant you are after — the method the experimental-design question asks for.

Moments of inertia

Where each moment of inertia comes from

Every one of these is an integral, not a fact to memorise. Choose a body to see the mass element, the set-up, and the evaluation.
