### Chapter 2 - Newtonian Mechanics

Term | Definition |
---|---|

Force | push or pull on an object; = ma; kgm/s^2 = N |

Mass | m; scalar; inertia; kg |

Weight | = mg; vector; gravitational attraction to the Earth; N |

Newton's First Law | a body at rest or in motion with constant velocity will remain that way unless acted upon by a force |

Newton's Second Law | F = ma; F direction = a direction |

Newton's Third Law | For every action, there is always an equal but opposite reaction; Fba = -Fab |

Gravitational Force Eq | F = Gm1m2/r^2 |

Translational Eq | Sum of the force vectors equals 0 |

Rotational Eq | Torque |

Torque Equation | T = rFsin theta |

Torque in clockwise direction is... | negative |

Find max Torque at | sin 90 degrees cuz it = 1 |

Static Friction | force which must be overcome to set an object in motion; opposes motion; to get object moving from rest |

Kinetic Friction | to keep object moving; (mu)(F normal) |

When two blocks are connected on conveyor belt... | their acceleration is equal and their tensions are equal; add equations together to find acceleration and Tension |

Uniform Circular Motion Acceleration and Force Equations | a = v^2/r; F centripetal = (mv^2)/r = ma |
