What is the unit of measurement for velocity? | Meters per second |

What is the unit of measurement for distance? | Meter |

What is the equation to find impulse? | Force x Time = Impulse |

What are the 2 equations for velocity? | Distance divided by time = Velocity, and acceleration due to gravity times time |

What is displacement? | The change in position |

What is constant velocity? | Where the velocity is the same. |

What is average velocity? | The total displacement, divided by the time taken. |

What is instantaneous velocity? | The velocity at one specific moment. |

What are the 2 equations to get acceleration? | The final velocity, minus the initial velocity divided by time, and force divided by mass. |

What is a force? | Anything with the ability to push or pull. |

An object at rest will stay at rest and an object in motion will continue in motion with the same velocity unless acted on by an outside force is... | Newton's first law. |

What is inertia? | The property of an object that resists change of motion. |

What is the unit of measurement for force? | Newton |

What is net force? | The total of all forces acting on an object. |

What is free fall? | Acceleration due to the force of gravity. |

What is the acceleration due to gravity on Earth? | 9.8 m/s^2 |
