Specification Point

Describe the effects of forces between bodies such as changes in speed, shape or direction

Forces can affect bodies in several different ways:

They can change their speed

They can change their direction

They can change their shape

Specification Point

Identify different types of force such as gravitational or electrostatic

Forces can take many different forms:

Forces you should be aware of include:

Weight – the name given to the force of gravity on a mass.

Electrostatic force – the force between two charges

Thrust – a force pushing an object forward (such as the force from a car engine)

Air resistance (or drag) – the friction of the air on a moving object.

Upthrust – the force of a fluid (such as water) pushing an object upwards (making it float)

Compression – forces that are squashing an object

Tension – forces that are stretching an object.

Reaction force – a force due to contact between two objects.
