Physics is a science that describes how things work. Almost everything around us can be explained in terms of the principles of physics. With the use of practical demonstrations related to common activities, this program investigates some of the key concepts of physics. Using a drum kit we look at how sound works, how we make it, and how it gets around. We investigate electricity and electromagnetism and compare the similarities between a remote control car and a mobile phone charger. Finally, we take a look at radioactivity and discover a radioactive device that can be found in almost every family home.
