Science: Vernier - Friction
by Vernier Software & Technology

Published on June 09, 2008

Overview

Students study how the nature of two materials in contact, and the smoothness of their surfaces affect the magnitude of the sliding force of friction. They use a force sensor to measure frictional force for different surfaces.

Key Steps

  • Image

    Set up the Force sensor connecting it to a wooden block using a paper clip. Slowly pull the block across a smooth surface. Once the block is moving press start to begin collecting data.

  • Image

    Determine and record the force used to pull the block using the force vs. time graph displayed.
