### Newton's toy box

Term | the rate of change in velocity |
---|---|

action force | a force exerted on a subject |

air resistance | the force of air pushing against a moving object |

conservation of energy | the amount of energy in a closed system remains constant over time |

conservation of momentum | for two objects subject only to their mutual interactions, the total momentum of the objects remains constant in time. P=mv. This is equivalent to Newton's third law of motion |

elastic potential energy | the term used to describe the energy stored in a compressed or stretched object (usually a spring or rubber band) |

energy | the ability to do work (or to produce change) |

force | a push or pull |

freefall | the condition of an object falling in a gravitational field |

friction | a resistance force opposing motion |

gravitational potential energy | the energy possessed by an object that can fall |

gravity | the force of attraction between masses |

inertia | the property by which an object tends to remain at rest or in uniform straight-line motion. |

kinetic energy | the energy possessed by an object because of its motion |

mass | the amount of matter an object contains |

microgravity | almost weightless conditions; only very small forces remain. This is the term used by NASA to describe the in-orbit environment |

momentum | the product of an object's mass multiplied by its velocity. Momentum is conserved quantity within a closed system. |

Newton's first law of motion | an object will remain at rest or in uniform motion unless acted on by an unbalanced external force |

Newton's second law of motion | the acceleration of an object is inversely proportional to its mass and directly proportional to the resultant external force acting on it (F=ma). A greater unbalanced force causes a greater acceleration of an object in the direction of the force. The m |

Newton's third law of motion | Forces always occur in pairs. If object A exerts a force on Object B, an equal but opposite foce is exerted by Object B on Object A. For every action there is an equal and opposite reaction. |

parabola | One possible path of an object falling freely in a gravity field. A tossed ball follows a parabolic arc |

potential energy | the energy required to place an object in a position. This energy is stored in the object until the object moves |

reaction force | the force exerted by an object experiencing an action force. The reaction force is equal to the action force, but in the opposite direction |

speed | the distance traveled by an object divided by the time required to cover the distance |

velocity | a measure of the speed and direction of an object's motion |

weight | the strength of the gravity force pulling down on an object. |

acceleration | the rate of change in velocity |

gravity support force | the force that opposes gravity |
