### Momentum, Energy, and Collisions (MBL) Pre-lab Assignment

Your name: _____________________

Print this page, record your answers on it, and show it to your lab TF at the start of your lab session.
In the experiment you will analyze several 1-D collisions to see whether momentum and/or kinetic energy are conserved. We'll analyze three simulated collisions here using the same methods.

Collision | Initial momentum of blue cart | Initial momentum of red cart | Final momentum of blue cart | Final momentum of red cart | Total initial momentum | Total final momentum | Ratio of total final/total initial |

1 | 0 | ______ | ______ | ______ | ______ | ______ | ______ |

2 | 0 | ______ | ______ | ______ | ______ | ______ | ______ |

3 | 0 | ______ | ______ | ______ | ______ | ______ | ______ |

Is momentum conserved in these collisions? Justify your answer.

Collision | Initial K of blue cart | Initial K of red cart | Final K of blue cart | Final K of red cart | Total initial K | Total final K | Ratio of total final/total initial |

1 | 0 | ______ | ______ | ______ | ______ | ______ | ______ |

2 | 0 | ______ | ______ | ______ | ______ | ______ | ______ |

3 | 0 | ______ | ______ | ______ | ______ | ______ | ______ |

Is kinetic energy conserved in these collisions? Justify your answer.

Classify each of these collisions according to the definitions given in the lab write-up.

Collision 1: | Super-elastic | Elastic | Inelastic | Completely inelastic |

Collision 2: | Super-elastic | Elastic | Inelastic | Completely inelastic |

Collision 3: | Super-elastic | Elastic | Inelastic | Completely inelastic |
