The forces builder draws force diagrams on GCSE graph paper. Four modes cover collinear forces, resolving into components, finding a resultant and free body diagrams, with your values on the arrows.
A hand-built replica of the real builder page, not a screenshot. Every control shown exists in the product.
Force arrows drawn by hand end up different lengths for equal forces, and pupils read meaning into the wobble. Here the arrows are drawn to scale on graph paper, so equal means equal and the resultant is visible before anyone calculates it.
Set the values to match the question you are teaching, export the diagram for a worksheet, and turn on steps on canvas when the class needs the working shown.
Diagnostic multiple choice. Each answer reveals what the class does and doesn't understand.
Answers revealed when you click. Great for starters or extension questions.
Match keywords to their definitions. Great for prior learning or end-of-lesson review.
Every tool turns a few inputs into a clean, exam-ready diagram.
Equation selection, rearrangement and substitution practice, step by step.
Before and after collision diagrams with selectable unknowns and a step-by-step reveal.
Graph-paper lens, focal points and object for teaching ray construction.
Curated GCSE nuclear equations covering alpha, beta, fission, fusion and decay chains.
Build circuits from standard GCSE symbols and components.
Practical results tables with repeat readings, a mean and an optional anomaly, plus curated reference data.
Upload any diagram and the labels are suggested for you to drag, edit and blank.
