From Appdios Inc.:
PhyDios is an interactive, immersive way of learning physics. Design, Play, Learn, Share, Challenge, Comment, and do more. Unleash your creativity. It is a great simulation tool to experience physics using your own hands. Use simple drawing tools to build elaborate worlds, your own game, projects and even a quiz using rigid bodies, fluids, pivots, springs, ropes, rods, layers, motors, magnet, killer, immortal. With PhyDios we motivate students to learn physics while having fun at it. Only your imagination can hold you back. Features Real 2D physics object interaction. Simple Drawing tools easy to use drawing tools to create striking scenes. Use free tool for free hand drawing, smart tool for shape recognition. Connection tools connect bodies using spring, rope, rod, or pivot. Customize move, rotate, scale, delete, add text to body, change color, auto color, use photo library, physics pad images to create interesting scenes. Accelerometer enable accelerometer to use your device motion to change gravity. Gravity change its direction and magnitude. Set it to 0 for free space. Experiment how bodies react to change in gravity. Boundary remove/add roof, floor, walls. Effects make it rain; make it snow. Music add your favorite music or record your own voice for the background score. Physics Properties play with different weights, change elasticity, friction, inertia, torque, angular velocity. See how these properties affect bodies. Advance features turn objects into magnet, attach motor to it, liquefy it, make it a killer or grant it immortality. Layer physics pad provides 2 layers of interaction. Change layer to avoid collision between bodies. Storyboarding - take screenshots, write notes to explain the flow of your project.Analysis - Graphical and tabular analysis of real time values. export as excel for further studies. Save your work for later, update it anytime. Broadcast your creation, get rated, get feedback from other users. Post it on Facebook, Tweet and share it with friends. And most importantly, have Fun!
