### physics formulas

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

average speed(v) | distance(d) / time(t) |

average velocity(v) | velocity final (vt) + velocity initial (vi)/2 |

acceleration(a) | velocity final (vt) - velocity initial (vi)/change in time(t) |

projectile motion: distance(d) | velocity(v) x time(t) |

vertical motion: | velocity final (f) = vertical initial + at d = 1/2at^2 + vt vf^2 = vi^2 + 2ad |

Newton's First Law: force(F) | constant of proportionality(k) x acceleration(a) |

Newton's Second Law: force(F) | mass(m) x acceleration(a) |

Weight(W) | mass in kilograms(m) x gravity(g) |

gravity(g) | 9.8m/sec^2 |

d | vt |

v(f) | v(i) + at |

d | 1/2at^2 + v(i)t |

v(f)^2 | v(i)^2 + 2ad |

centripetal acceleration:a(c) | speed of the object in meters per second:c:v^2 / radius of the circle: r |

Kinetic energy: KE | 1/2mv^2 |

potential energy: PE | mgh |
