Friction
Learn how friction causes a material to heat up and melt. Rub two objects together and they heat up. When one reaches the melting temperature, particles break free as the material melts away.

Teaching Resources
Main Topics
- Friction
- Thermodynamics
- Heat
Sample Learning Goals
- Describe a model for friction a molecular level.
- Describe matter in terms of molecular motion. The description should include: diagrams to support the description, how the particle mass and temperature affect the image, what are the differences and similarities between solid, liquid and gas particle motion; how the size and speed of gas molecules relate to everyday objects.
