# McCormack- Newton

### McCormack-Newton's Law Test

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

Motion | A change in position over time |

Speed | Distance over time (s=D/t) |

Units for Speed | meters per second (m/s) |

Acceleration | Change in speed over time (Vf-Vi/t) |

Units for Acceleration | Meters per second squared (m/s^2) |

Velocity | Speed with direction |

Inertia | Objects in motion tend to stay in motion & objcects at rest tend to stay at rest |

Gravity | A force of attraction based on mass and distance |

Force | A push or pull measured in Newtons (N) |

Acceleration due to Gravity | 9.8 m/s/s |

Momentum | Momentum (P) = mass x Velocity P=mV Mass in motion |

Newtons (N) | Force Units, Kg x m/s/s |

Newton's 1st Law of Motion | Inertia, Objects at rest tend to stay at rest while objects in motion tend to stay in motion |

Newton's 2nd Law of Motion | Force is directly related to mass & acceleration. F=ma |

Newton's 3rd Law of Motion | Every action has and equal but opposite reaction. |

Weight | The effect of gravity on mass Weight = mass x 9.8 m/s/s |

Newton's 1st law of Inertia | A book sitting on the table will not move unless an unbalance force is acting on it |

Terminal Velocity | The velocity reached when air resistance is equal to acceleration due to gravity |

Balance Force | Equal but opposite forces that cancel out and result in no motion |

Unbalance Force | Unequal and opposite forces that results in motion |

Friction | A force opposite to motion resulting from the direct touch of two objects. |

Newton's 2nd Law of Acceleration | What Law gives us the formula to calculate weight? W= 9.8m/s^2 x mass |

Newton's 3rd Law of Action/Reaction | What Law says that book sitting on the talble has and opposite force pushing up on it? |

Static Friction | Friction between two objects at rest |

weight = m x g, 1,000 grams (1 kg)x 9.8 = ___9.8____ Newtons (round to 10 N) | the weight of 1,000 grams = |

Mass | The amount of stuff in an object that cannot change based on position in the Universe |

Newton's 1st Law, Inertia | A student flying off skate board that has hit a curb is an expamle of |

Newton 2nd Law , F=ma, F = .1 x 2,500 = 250 N | Newton's 2nd Law of Acceleration is used to calculate the force of a bullet (.1 kg @ 2,500 m/s)F=ma |

Newton's 3rd Law of Action/Reaction | Which Newton Law explains when a rocket engine pushes one way and rocket goes the opposite direction? |

Newton Law of Inertia | A train takes a mile to come to a stop is an example of |

Volume | The amount of space an object takes up, measured in Liters. |

Calculate the weigth of a student who is 55 kg, g= 9.8 m/s2 | Weight = mg (F=ma) W = 55 kg x 9.8 m/s2 = 539 N |

Two objects hit at the same time since acceleration of gravity is always 9.8 m/s2 on Earth | Two different mass objects dropped at the same time will |
