  • Independence of Velocity

    Book Chapter |

    This inquiry activity should be completed before discussing with students that a projectile’s motion in the vertical direction is independent of its motion in the horizontal direction. As long as students use their…

  • Terminal Velocity

    Book Chapter |

    This lab is an inquiry activity in that students have not been exposed to the idea of terminal velocity, though they are using skills that they already have to analyze the balloon’s motion. The lab is both a review of…

  • Acceleration and Velocity

    Book Chapter |

    The purpose of this lab is to introduce students to the core idea of forces and motion by having them explore the relationship between acceleration and velocity to determine ”How Does the Direction of Acceleration…

  • Quickly Teaching Speed, Velocity, and Acceleration—Part 2

    Journal Article |

    In the February 2019 issue we looked at teaching speed and velocity. Now we’re ready to tackle acceleration.

  • Focus on Physics: Quickly Teaching Speed, Velocity, and Acceleration—Part 1

    Journal Article |

    Motion is best learned by keeping it simple—by neglecting the effects of air resistance, as well as the effects of buoyancy, spin, and the shape of moving objects.
