As answered by people managing Motion Magic Physics Simulator and PDFShift.
Motion Magic Physics Simulator's answer
College physics students, Community college classes, and just Independent learners!
Motion Magic Physics Simulator's answer
Motion Magic lets you build and explore physics problems the way you think about them. You place objects, push or pull them, change numbers, and see exactly how everything moves immediately.
Motion Magic Physics Simulator's answer
Most tools only show preset demos. Motion Magic lets you experiment, make mistakes, adjust ideas, and actually understand what the motion is doing instead of guessing from a diagram.
Motion Magic Physics Simulator's answer
Students taking their first introductory physics class who need something clearer than a textbook and more hands-on than a calculator.
Motion Magic Physics Simulator's answer
Motion Magic started from one problem: students get stuck trying to connect formulas to real motion. It was built to give them a space where they can try things out, see the results, and finally make sense of what’s happening.
