Sensible Science Simulations

Buoyancy: Change every variable (except viscosity) Show how the buoyant force is related to the densities of the object and the fluid, volume of the object, volume of the displaced fluid, acceleration due to gravity. Vectors show the buoyant force, the force of gravity, the normal force, and, if you wish, a push or a pull. Place the object in any position, or push or pull the object vertically, and view from any angle by rotating, panning or zooming the animation). Choose to display the calcula

3D Ray Diagram Sim...The standard ray diagram in 3D... Select:Focal length (converging or diverging lens)Object distanceObject heightLens radiusDistance of optional screen from lensChoose to see or not see virtually all aspects of the ray diagram except the lens itself.Adjust viewing angle using mouse/trackpad/fingerZoom using mouse wheel/trackpad/fingers This simulation opens in all recent popular computer browsers (Chrome, Firefox, Safari, Edge, Opera) and Chromebooks. ProjectileSim does work

A free HTML5 3-D simulation that draws a transverse sine wave of variable frequency, wavelength, amplitude and speed using a 'machine'.  This simulation opens in all recent popular computer browsers (Chrome, Firefox, Safari, Edge, Opera) and Chromebooks .   Wave Maker works on iPads and tablets... iPhones and android phones are a bit small..

Moving the computer mouse (or your finger) creates position/time and velocity/time graphs...And also distance/time and speed/time graphs... A simple app that graphs the position, velocity, distance, and speed of a computer  mouse (or your finger) against time.   This app opens in all recent popular computer browsers (Chrome, Firefox, Safari, Edge, Opera) and Chromebooks. MouseMoveGraph  does work on Android things, iPads and iPhones, although iPhones are a bit small.
