# Distance and Speed

### Grade 10 distance and speed study cards

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

How can you tell teh acceleration of a car on a speed time graph? | The slope of the line indicates the acceleration |

What is high positive value? | Rapidly increasing speed ( a line with a steep slope) |

What is low positive value? | Slowly increasing speed ( a line with hardly any slope) |

What is Zero value? | There is no acceleration ( there is a horizontal line across the graph) |

What is negative value? | The speed is decreasing ( the slope is negative) |

What does the area under the speed time graph indicate? | The area under the line ona speed time graph is the total distance traveled. |

How can you tell that an object is accelerating? | As long as there is a slope to the lone the object is accelerating |

What is Instantaniouse speed? | Is the sped at the particular moment in time, for any object moving a constant speed the instantaniouse speed is the same |

How do you find intantaniouse speed on a distance time graph? | A target is a straight line that just touches the slope of time on that line, the slope of this line is the instantaniouse speed |

How do you find the instantaniouse speed on a speed time graph? | For the speed time graph you just go straight down from the moment in which you want to find the speed for. |

How do you find the instantaniouse speed on a distance time graph if the speed is changing? | |

General formula for average speed | Vav = delta d/ delta t |

General formula for average acceleration | Aav = delta v/ delta t |
