Electromagnetism
A magnetic field is also produced around any electrical conductor when current is flowing. For example, a magnetic field is ...
Energy resources
We use energy in different forms every day to provide us with the necessities we need to survive such as ...
Energy transfers
Energy is measured in the unit joule (J) and is needed by all objects to change shape, size or position. ...
Forces and movement
The way an object moves depends on its mass and the size and direction of the resultant force acting upon ...
Forces and shape
In this section, we will learn how different objects and their size affect the impact of the forces applied to ...
Friction and braking
When the brakes on a vehicle are applied, the amount of friction between the wheels and the surface it touches ...
Gravitational forces
Mass The mass of an object is the amount of matter or ‘stuff’ it contains. The more matter an object ...
Gravitational potential and kinetic energy
As we have seen in this unit already, the work done in moving an object is equal to the energy ...
Ionising radiation
Isotopes share the same chemical properties as they have equal numbers of electrons. However, different isotopes of the same element ...
Kinematics
Kinematics is just a fancy name for the study of motion and the way that things move around. It is ...
Materials, friction and energy
Insulating materials do not conduct electricity and have no charge overall. However, they do have the potential to become charged ...
Newton’s laws of gravity
Sir Isaac Newton presented the theory of gravity. This explained the movements of planets and provided an explanation of how ...
