JavaScript => var mass: float;
C# => float mass;

Description 描述

Mass of the rigidbody.

该刚体的质量。

The mass is given in arbitrary units but the basic physical principles of mass apply. From Newton's classic equation force = mass x accelelation, it is apparent that the larger an object's mass, the more force it requires to accelerate it to a given velocity. Also, mass affects momentum, which is significant during collisions; an object with large mass will be moved less by a collision than an object with lower mass.

质量的单位是主管给定的，但应用质量的基本物理原理。遵从经典的牛顿方程式 力 = 质量 X 速度，这很明显较大的对象质量，要更多的力需要加速到一定的速度。另外，质量影响动力，在碰撞期间尤其重要；具有较大质量的对象碰撞比具有较小质量对象移动慢。
