Centripetal | | A type of collision where momentum is conserved, but KE is not. |

Elastic | | The slope of a position-time graph, can be or - |

Velocity | | The rate of change of velocity with time |

Potential | | The product of force and distance when they act in the same direction |

Energy | | A push or pull on an object due to the interaction of two objects. |

Work | | A term used with "energy" or "friction" that implies motion |

Speed | | A term often used with "acceleration" that literally means "center-seeking" |

Newtons | | A force that exists between any two masses separated by a distance |

Acceleration | | A change in momentum |

Gravity | | A quantity with magnitude |

Inertia | | How fast an object is traveling |

Impulse | | The tendency for an object to resist changes in velocity; directly related to its mass. |

Power | | The type of force that is directed perpendicular to a surface |

Force | | The change in position of an object (from start to finish) |

Displacement | | The rate at which work is done; the rate at which energy is used. |

Kinetic | | A force that opposes motion when two surfaces slide past each other |

Normal | | Inertia in motion |

Period | | The size of a given quantity - how much? how fast? how far? etc. |

Inelastic | | A term used with "energy" that implies stored energy. |

Static | | The units for mass when using an equation |

Vector | | The number of circles or cycles per unit of time |

Friction | | A term used with "friction" that implies a lack of motion |

Momentum | | The amount of time for a complete circle or cycle |

Frequency | | A type of collision where both KE and momentum are conserved |

Kilograms | | The units used to measure force |

Magnitude | | The ability to do work |
