The potential energy between two objects due to long-distance forces can be thought of as being stored in a field. When the objects move due to the field forces, the energy stored in the field decreases

In this course you will learn about:
In this unit you will learn about different materials by investigating and observing the behaviour of their properties. This will include learning about the differences between metals and non-metals; whether they are isolators or conductors of electricity and heat, whether they are magnetic, how dense they are and whether they are acidic or basic.
By the end of this course you will:
This YouTube video investigates the structure and composition of the sun.
These four short online lessons cover the following:
This online resource investigates the internal structure, outer layers and surface features of the sun.
