Question | Answer |

What is the formula for speed? | Speed = distance / time |

On a distance-time graph, the gradient is equal to what? | speed |

The steeper the graph the... | faster its going |

If the line is going downhill what does this mean? | coming back to the start |

A Flat section on this type of graph means? | stopped |

How do you calculate the gradient? | vertical / horizontal |

what is the difference between velocity and speed | speed only has a number wheras velocity has direction aswell |

In velocity-time graphs the gradient equals? | acceleration |

flat sections on this graph are? | steady/constant speed |

The uphill sections equal? | acceleration |

downhill sections equal? | deceleration |

the area under any section of the graph is equal to? | the distance travelled in that amount of time |
