Topic Revision
There are some activities in BOLD throughout the different headings which you are encouraged to write revision notes about in your books.
Forces
- A force is a push or a pull or a turn
- List some examples of forces.
- Balanced and unbalanced forces and calculate net force.
- Forces can speed up, slow down or change the direction of an object.
- Forces can be applied by Contact or Non-Contact (at a distance) and those applied at a distance have a field around them.
- Forces have size and direction and are measured in Newtons (N)
- Measure the size of forces.

Frictional forces
- Friction is a contact force which acts in the opposite direction to motion
- Friction is both good and bad.
- Identify where friction is good and technology is used to increase it
- Identify where friction is bad and technology is used to decrease it
- Importance of friction in everyday situations (starting and stopping)
Electrostatics
- Describe ways objects become charged.
- Identify the two types of charge (+ & -)
- State the rules of attraction & repulsion.
- Identify that there is a field around a charged object.
- Draw diagrams of the effect of charged objects on each other
- Give examples of everyday situations of electrostatic forces
Magnets
- Identify the two types of magnetic pole (N & S)
- State the rules of attraction & repulsion.
- Define the term ‘field’ and identify the field around a magnet.
- Draw magnetic fields around bar magnets
- Describe the effect of magnetic poles on each other
- Identify everyday uses of magnets and electromagnets
Gravity
- Identify that all objects exert a force of gravity on all other objects
- Identify examples of gravitation forces
- Define mass and weight and the difference
- Identify that gravity acts on us through a field.
