Defined as useful work per quantity of energy or Work In/Work Out or Mechanical Advantage/Ideal Mechanical Advantage | |

Study where the smallest discrete values (quanta) of matter and energy become relevant | |

The sum of the potential & kinetic energy of an object | |

Study of the physical properties of light | |

An object at rest will remain at rest and an object in motion will remain in motion until acted upon by an outside force/inertia | |

Circular motion where the speed of orbit is constant | |

It is impossible to reduce any system to absolute zero in a finite series of operations/A perfectly efficient heat engine cannot be created | |

Measure of stiffness of elastic material/defined as the ratio of stress (force per unit area) to strain/also 'tensile modulus' or 'elastic modulus' | |

Any type of back and forth motion where there is no damping (e.g. ideal springs/ideal pendulums/LC circuits) | |

Measure of force amplification achieved by using a tool (any mechanical device)/levers, gears, block & tackle/equal to Force Out/Force In or Velocity In/Velocity Out | |

The change in energy of a system is the amount of energy added to the system minus the energy spent doing work/Law of Conservation of Energy | |

Pseudo-force directed outward from center point | |

Study of fundamental particles and the forces of their interactions | |

2 systems each in thermal equilibrium with a third system are in thermal equilibrium with each other | |

The sum of the forces equals mass x acceleration | |

Any 2 bodies in universe attract each other w/force directly proportional to product of their masses & inversely proportional to the square of distance between them | |

Study of the physics of heat | |

For every action there must be an equal but opposite reaction | |

Study of how electrons and photons interact at the quantum mechanical level | |

Bodies in orbit will sweep out equal amounts of area in equal times | |

The study of physical properties in low temperature situations, far below the freezing point of water | |

Branch of physics/chemistry based on probability/explains how properties of atoms (mass, charge, structure) determine physical properties (conductivity...) | |

Study of the theory that all fundamental particles are vibrations of one-dimensional strings of energy in a higher-dimensional universe | |

Laws of physics governing orbiting bodies/mathematically proven by Newton | |

Energy stored in a spring/by gravity/in a capacitor/in an inductor | |
