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.

Introducing Alpha, Beta and Gamma. Describes characteristics of each.
