Slide 2 - Slide
previously in physics class..
A force is a physical property which can alter up to
three effects.
It can change the shape of an object.
It can change the speed of an object.
It can change the direction of the speed of an object.

Today
After today you will be able:
-recognise and name different types of forces.
-to classify forces into the two different categories of forces.
Slide 4 - Slide
types of forces
There are many types of forces. The type of force has the name of how the force came to be. We also add the initial of the type to the symbol in subscript.
Example: Spring force, it's a force exerted by a spring.

examples of types of forces
There are many types of forces.
A couple common ones are:
-gravitational force
-friction force
-applied force
Slide 6 - Slide
Air resistance force
Gravity force
Spring force
magnetic force
Normal force
Tension force
applied force
Friction force
Slide 7 - Drag question
two categories of forces
There are two categories of forces.
Forces that work on contact and forces
that can work over a distance. contact forcesand non-contact forces
example:
Adhesive force only works on contact.
Magnetic force on the other hand can work over a distance.
