  1. The Use of Force Sensors and a Computer System to Introduce the Concept of Inertia at a School

    Bogdan F. Bogacz & Antoni T. Pedziwiatr

    A classical experiment used to introduce the concept of body inertia, breaking of a thread below and above a hanging weight, is described mathematically and presented in a new way, using force... More

  2. Characterization of Transiting Exoplanets by Way of Differential Photometry

    Michael Cowley & Stephen Hughes

    This paper describes a simple activity for plotting and characterizing the light curve from an exoplanet transit event by way of differential photometry analysis. Using free digital imaging... More

  3. Magnetic Force and Work: An Accessible Example

    Joshua Gates

    Despite their physics instructors' arguments to the contrary, introductory students can observe situations in which there seems to be compelling evidence for magnetic force doing work. The... More

  4. The Bounce Meter

    John Nunn

    This paper describes how a microphone plugged in to a normal computer can be used to record the impacts of a ball bouncing on a table. The intervals between these impacts represent the "time... More

  5. Direct Measurement of the Speed of Sound Using a Microphone and a Speaker

    José A. Gómez-Tejedor, Juan C. Castro-Palacio & Juan A. Monsoriu

    We present a simple and accurate experiment to obtain the speed of sound in air using a conventional speaker and a microphone connected to a computer. A free open source digital audio editor and... More

  6. Using Tablets as Tools for Learner-Generated Drawings in the Context of Teaching the Kinetic Theory of Gases

    A Lehtinen & J Viiri

    Even though research suggests that the use of drawings could be an important part of learning science, learner-generated drawings have not received much attention in physics classrooms. This paper ... More
