Following on from thermal energy1, this resource focuses on the relationship between change of state and temperature.

Introducing the relationship between thermal energy, temperature and kinetic energy of particles.

Building on the ideas from Resultant Force1. This work analyses a skydiver in freefall who then pulls his parachute. How the forces acting vary and how this changes the resultant force and hence the acceleration. There is a Resultant Force3 file which assesses the learning from this work.

This work matches the characteristics of the waveform to the pitch and volume of a sound.
