Review Friction Key COncept Builder

SLANT: Friction and the law of conservation of energy

  1. Sometimes friction makes it look like The Law of Conservation of Energy is being broken.

  2. Friction is a force that resists sliding of two surfaces that are touching.

    • converts kinetic energy (motion) into thermal energy.

  3. All surfaces have some friction

    • rough pavement (high friction)

    • ice (low friction)

  4. friction “wastes” mechanical energy

    • lubrication (oil) and bearings) reduce friction

    • make a bike easier to ride
