Question | Answer |

Symbols | Speed = (M/S) - Metre per Second Distance = (M) - Metres Time Taken = (S) - Seconds / = Divide Acceleration = (M/S) to the power of 2 Momentum = (kg M/S) Mass = (kg) - Resultant Force = (N) - Newtons |

Speed Equation | Speed = Distance Travelled / Time Taken |

Distance Equation | Distance Travelled = Speed X Time Taken |

Time Taken Equation | Time Taken = Distance Travelled / Speed |

Acceleration Equation | Acceleration - Change in Velocity / Time Taken |

Distance - Time Graph | Gradient = Speed Flat sections mean its Stationary Downhill means its going back to the start Steeping curve means its speeding up Levelling off Curve means its slowing down |

Calculate Distance - Time Graph | Use scales on the Axis to work out the gradient Speed = Gradient = Vertical / Horizontal |

Velocity | Velocity is a more useful measure of motion. It describes both speed and direction Velocity can be negative, for example is a car turns around |

Acceleration | Change in Velocity or Speed |

Force | Forces occur when 2 objects interact |

Reaction Force Example | If a was on a table then the book is pushing down on the table with a force equal to the weight. The table also exerts an equal and opposite force |

Friction | Friction is a reaction force - It happens as a result of an applied force |

Arrow on a Force - Diagram | Length - Size of the Force Direction - Direction of the Force |

Reaction on a Surface | If an object is resting on a surface it pushes downwards (because of its weight) |

Resultant Force | Overall force acting on an object |

Momentum Equation | Momentum = Mass X Velocity |

Car Safety | Crumple Zones Airbags Seat Belts |

Work Done | Energy Transferred |

Kinetic Energy | Force Created by Movement |

Kinetic Energy Equation | Kinetic Energy = 0.5 X Mass X Velocity Squared |

GPE | GPE - Gravitational Potential Energy Height Energy |

GPE Equation | GPE = Weight X Vertical Height Difference |

Falling Objects Means | Kinetic Energy Gained = GPE Lost |
