Analysis
1.Determine the momentum (mv) of each cart before the collision,after the collision,and the total momentum before and after the collision.Calculate the ratio of the total momentum after the collision to the total momentum before the collision.Enter the values in your data table.
2.Determine the kinetic energy (½ mv2) for each cart before and after the collision.Calculate the ratio of the total kinetic energy after the collision to the total kinetic energy before the collision.Enter the values in your data table.
3.If the total momentum for a system is the same before and after the collision,we say that momentum is conserved.If momentum were conserved,what would be the ratio of the total momentum after the collision to the total momentum before the collision?
4.If the total kinetic energy for a system is the same before and after the collision,we say that kinetic energy is conserved.If kinetic were conserved,what would be the ratio of the total kinetic energy after the collision to the total kinetic energy before the collision?
5.For your six runs,inspect the momentum ratios.Even if momentum is conserved for a given collision,the measured values may not be exactly the same before and after due to measurement uncertainty.The ratio should be close to one,however.Is momentum conserved in your collisions?
6.Repeat the preceding question for the case of kinetic energy.Is kinetic energy conserved in the magnetic bumper collisions?How about the Velcro collisions?Is kinetic energy consumed in the third type of collision studies?Classify the three collision types as elastic,inelastic,or completely inelastic.

1.确定每个小车上的势头（毫伏）的碰撞前,碰撞后,与前和碰撞后的总动量.计算碰撞前的总动量的碰撞后的总动量的比例.输入你的数据表中的值.
2.购物车为每个确定的动能（½MV2）之前和之后的碰撞.计算的总动能,碰撞到碰撞前的总动能后的比率.输入你的数据表中的值.
3.如果一个系统的总动量是相同的前,后碰撞,我们说的动量是守恒的.如果是保守的势头,这将是碰撞前的总动量的碰撞后的总动量的比?
4.如果一个系统的总动能碰撞之前和之后是相同的,我们说,动能守恒.如果是保守的动能,这将是在碰撞前的总动能碰撞后的总动能的比例?
5.对于六分,检查的势头比例.即使对于一个给定的碰撞动量是守恒的,测量值可能不完全一样的前,后,由于测量的不确定性.比例应该是接近1,但是.是的碰撞中动量守恒?
