Many pupils see friction as a phenomenon, rather than as a force.

  • Friction between solid surfaces (11-16)

    Source - Practical physics/ Force and motion/ Friction, turning and other effects

    This resource explores the factors that affect the force of friction.

  • Visualising what happens at surfaces for grip and slip (5-11)

    Source - SPT/ Mf03TA07

    This activity is designed to help children describe friction by:

    • recognising that sliding rough surfaces past each other has a warming effect
    • recognising that grip forces vary as the surfaces vary

  • Friction (11-14)

    Source - SPT/ Fo02PN08

    When two surfaces are in contact there is a force acting on each surface that acts in a direction to stop them moving past one another.

    (This study aimed to measure the effect of using 'bridging' analogies (analogies with intermediate examples) to address the preconceptions of high school physics students. The sample consisted of 3 experimental groups across 2 schools (comprising 150 students) and 2 control groups across 2 schools (comprising 55 students). Data was collected using pre- and post-intervention tests, and was analysed using a t-test.
