本程序设计了一个以跷跷板为原型的图像模型。该模型由一个长方形，两个正方形 和一个三角形组成-This procedure is designed as the prototype of a seesaw image model. The model consists of a rectangular, square and a triangle composed of two

一个小跷跷板，两个小球在随着跷跷板上下。-A seesaw, two small ball in with the seesaw up and down.

使用Unity3D验证杠杆原理，包括搭建或引用场景，然后通过附加刚体的性质方块，搭建一个跷跷板，实现对杠杆原理的验证。-Use Unity3D verification of leverage, including the build or reference scenario, then additional rigid body block by nature, build a seesaw, the validation of the lever principle.
