Electrostatics
When some materials are rubbed, they become charged with static electricity. They can then
attract other materials. The force of friction causes charging. This effect can be used in some
dusting brushes. The brush becomes charged and attrac
Radioactivity
Everything around us is made up of atoms. Each atom has a central nucleus, with
electrons orbiting around it.
The nuclei of most atoms are stable; however, in a small
number of atoms, the nuclei are unstable. Radioactive

Radiation
Nuclear radiation occurs naturally and is around us all the time.
Radioactive decay occurs when a nucleus of an unstable atom breaks down and
emits ionising radiation.
There are 3 types of radiation:

Electricity from the Sun
The sun is a stable source of energy. It transfers energy to Earth as light and infra-red radiation.
Energy from the sun can be used to generate electricity directly. Photocells absorb light energy
and transform it into electrical
Heat and Temperature
The temperature of a substance tells us how much energy each particle has. It is a
measure of the average kinetic energy per particle in a substance. Heat is a
measure of energy. It tells us how much energy all of the particles have t

Albert EINSTEIN introduced his SPECIAL THEORY OF RELATIVITY in 1905. To
understand the theory, we will first review the background, the theoretical and
