动量守恒 恢复系数

English Answer：

Momentum conservation is a fundamental law of physics

that states that the total momentum of a closed system

remains constant, regardless of the interactions within the

system. In the context of a collision between two objects,

momentum conservation can be expressed as:

m1 v1i + m2 v2i = m1 v1f + m2 v2f.

where:

m1 and m2 are the masses of the two objects.

v1i and v2i are the initial velocities of the two

objects.

v1f and v2f are the final velocities of the two

objects.

The coefficient of restitution (COR) is a measure of

the elasticity of a collision. It is defined as the ratio

of the relative velocity of the two objects after the

collision to the relative velocity of the two objects

before the collision. Mathematically, the COR can be

expressed as:

COR = (v2f v1f) / (v1i v2i)。

where:

v1f and v2f are the final velocities of the two

objects.

v1i and v2i are the initial velocities of the two

objects.

The COR can range from 0 to 1. A COR of 0 indicates a

perfectly inelastic collision, in which the two objects

stick together after the collision. A COR of 1 indicates a

perfectly elastic collision, in which the two objects
