# OAT Physics

### Chapter 1 -Units and Kinematics

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

length | m |

mass | kg |

Force | N |

E/Work | Joule |

Time | sec |

Power Watt | |

Angstrom | 10E-10m |

nm | 10^-9m |

1 eV (electron-volt) | 1.6E-19J |

Kilo | 10^3 |

Mega | 10^6 |

Giga | 10^9 |

micro | -6 |

pico | -12 |

nano | -9 |

when multiplying | multiply mantissa, add exponents |

when dividing | divide mantissa, subtract exponents |

Sin 0 | 0 |

Cos 0 | 1 |

Sin 30 | i/2 |

Cos 30 | radical 3 over 2 |

Sin 45 | radical 2 over 2 |

Cos 45 | radical 2 over 2 |

Sin 90 | 1 |

Cos 90 | 0 |

Sin 180 | 0 |

Cos 180 | -1 |

Sin 60 | radical 3 over 2 |

Cos 60 | 1/2 |

Scalars | magnitude but NO direction; speed, mass, E, distance |

Vector | magnitude AND direction; force, velocity, displacement, acceleration, momentum |

resultant | vector sum |

Tan theta = 1 | theta = 45 degrees |

Kinematics | branch of mechanics dealing with the description of motion |

instantaneous speed | magnitude of instantaneous velocity; scalar |

instantaneous velocity | refers to a single instant of time (specific time) ; vector |

Avg speed | distance/time |

Avg velocity | displacement/time |

Avg Acceleration | rate of change of an object's velocity so (delta velocity/delta time) |

instantaneous acceleration | acceleration at one point of a particle's path |

acceleration due to gravity | object in free-fall; 9.8m/s^2 |

projectile motion | Vx is constant; a in x direction = 0 |

Motion EQ | 1. v = v0 + at 2. x-x0 = v0t + (1/2)at^2 3. v^2 = v0^2 + 2a(x-x0) |

At max height | v = 0 |
