### Science Motion

Question | Answer |
---|---|

What is the formula for acceleration? | Vf - Vs/Change in time |

What is the speed formula? | D/T |

What is the distance formula? | S x T |

What is the time formula? | D/S |

What are the units for momentum? | kg x m/s |

What is the momentum formula? | mass x velocity |

What is velocity? | the speed of an object and the direction of its motion |

What is motion? | a change in objects position relative to a reference point |

What is speed? | distance an object travels per unit of time |

What is acceleration? | rate in which velocity changes |

What is displacement? | the distance and direction of the objects change in position |

What is momentum? | the product of mass and velocity |

What is a reference point? | an object that appears to stay in place |

If the tree is not moving what is the reference point? | the earth |

If the tree is moving what is the reference point? | the sun, or outer space |

Can a moving object be used as a reference point? | yes |

If police are chasing a runaway car, why is the velocity of the car important information to have? | So you know the direction the car is going, and the speed of the car, so you can trap the car. |

What is the independent variable for the car ramp lab? | height of the ramp |

What are 4 controls for the car ramp lab? | 1. Ramp surface 2. Surface of ground car goes to 3. car 4. same distance |

What is positive acceleration? | acceleration in which velocity increases |

What is negative acceleration or deceleration? | acceleration in which velocity slowed down. |

What is centripetal acceleration? | acceleration that occurs in a circular motion, always changing direction |

What are the three types of acceleration? | negative acceleration, positive acceleration, and centripetal acceleration |
