  1. Conceptual and Laboratory Exercise to Apply Newton's Second Law to a System of Many Forces

    Carl E. Mungan

    A pair of objects on an inclined plane are connected together by a string. The upper object is then connected to a fixed post via a spring. The situation is first analysed as a classroom exercise... More

  2. An Inexpensive Digital Infrared Camera

    Allan Mills

    Details are given for the conversion of an inexpensive webcam to a camera specifically sensitive to the near infrared (700-1000 nm). Some experiments and practical applications are suggested and... More

  3. One-Dimensional Collision Carts Computer Model and Its Design Ideas for Productive Experiential Learning

    Loo Kang Wee

    We develop an Easy Java Simulation (EJS) model for students to experience the physics of idealized one-dimensional collision carts. The physics model is described and simulated by both continuous... More

  7. On the Use of a Standard Spreadsheet to Model Physical Systems in School Teaching

    Andreas Quale

    In the teaching of physics at upper secondary school level (K10-K12), the students are generally taught to solve problems analytically, i.e. using the dynamics describing a system (typically in the... More
