### Slope, Distance, Velocity, Time

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

The slope of a distance vs time graph is equal to | speed |

The slope of a speed vs time graph is equal to | acceleration |

What is the difference between average speed and instantaneous speed? | Average speed is total distance divided by total time. Instantaneous speed is speed you have at a specific point on the journey. |

What is the difference between speed and velocity? | Speed is how fast you are going over a certain distance. Velocity is speed and direction. |

What is the difference between acceleration and speed? | Speed is distance over time. Acceleration is how much your speed changes over time |

What type of acceleration is cruise control on a straight road? | zero acceleration |

What type of acceleration is applying brakes on a truck? | deceleration |

What type of acceleration is dropping a ball from the roof? | acceleration (due to gravity) |

What type of acceleration is a motorcycle parked in a parking log? | zero acceleration |

What type of acceleration is a car turning a sharp corner? | acceleration |

time = ? | distance divided by velocity |

distance = ? | velocity multiplied by time |

velocity (speed) = ? | distance divided by time |
