### vocab for physics

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

Newtons first law | Objects would stay still until you apply force . Objects would stop moving until you stop applying force |

Newtons second law | Force = Mass x Acceleration |

Newtons third law | For every action there is an equal and opposite reaction |

What is the unit for acceleration | M/s2 |

What is the unit for mass | kg (kilograms ) |

What is the unit for force | N (Newtons) |

Speed | distance over time |

mass | the amount of matter in an object |

inertia | an object's tendency to move in a direction |

Force | a push or a pull |

acceleration | a change in speed over time |

velocity | speed and direction |

Vector | a direction |

momentum | inertia in motion |

impulse | units of forts multiplied by units of time. |

SI | International Standard |

centi | 100 |

milli | 1,000 |

deci | 10 |

Kilo | 1,000 |

Gravitational Constant (G) | 6.67408 × 10^-11 |

Approximate gravitational force formula | F~ m1 x m2/d^2 |

Exact gravitational force formula | F= G m1 x m2/d^2 |

Newton's synthesis | Newton found that the laws of gravity works the same in space as well as earth. |

What kind of things determine gravitational force? | Mass and distance |

Electrical Energy | When electrons move through a wire. |

Radiant (Light) Energy | Different types of light (Colors, microwaves, radio waves) |

Nuclear Energy | Energy from the splitting and bonding of atoms. Fission and Fusion |

Thermal Energy | Heat caused by moving atoms |

Chemical | Energy stored in matter. (Ex. Fuel, food, explosives) |

Elastic Energy | Energy from compressing or stretching (crushing or pulling) |

Sound Energy | Vibrations of Matter |

Gravitational Energy | Energy that comes from falling from high places |

Mechanical Energy | When something moves. |

Kinetic Energy | Energy in motion |

Potential Energy | stored energy |
