# Newtons Laws

### A quick review of Newton's three laws and how they work

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

What is Newton's First Law | An object will continue its current state of motion unless acted upon by an outside force. This law is also known as the Law of Inertia. |

What is Newton's Second Law | The acceleration of an object is directly related to the net Force acting on it and inversely related to it's mass. F=ma |

What is Newton's Third Law | For every action there is an equal and opposite reaction. |

What is mass? | Mass is a mathematical representation of inertia. |

Which of Newton's Laws explains the phenomenon that allows you to pull a tablecloth from beneath cups and plates? | Newton's First Law |

Which of Newton's Laws explains the phenomenon a cannon kicking backwards when fired? | Newton's Third Law |

Which of Newton's Laws explains fact that pushing a truck with all of your might causes less (if any) acceleration to the truck. | Newton's Second Law |

An object is being pulled to the east with a force of 40 Newtons at the same time as it is being pulled to the west with a force of 20 Newtons. What is the net Force acting on the object? | 20 Newtons east |

What is the unit for Force? | Newton or kilogram-meter per second squared |

What is the acceleration of a 10 kilogram object being propelled by a 20 Newton net force? | 2 meters per second squared |
