Box2DJS is a JavaScript port of Box2D Physics Engine . To tell the truth, this is converted from Box2DFlashAS3 _1.4.3.1 in an automatic manner. (The reason why not Box2DFlashAS3_2.0.0 based is simply because I overlooked the renewal.)

If you have some requests or find any bugs, please tell me about them.

A bar above any quantity indicates that it is the average value of that quantity. If the acceleration is constant, then equations 1,2 and 3 represent a complete description of the motion. Equation 4 is obtained by a combination of the others. Click on any of the equations for an example.

Distance, Average Velocity and Time The case of motion in one dimension (one direction) is a good starting point for the description of motion. Perhaps the most intuitive relationship is that average velocity is equal to distance divided by time:

These motion equations apply only in the case of constant acceleration. It is assumed that x=0 at t=0 and that the motion is being examined at time t. After you have edited any box of motion data, click on the text or symbol for the quantity you wish to calculate. If it does not behave the way you expect, see the comments on the calculation.
