Friction

Friction

Friction is a force between two surfaces that are sliding, or trying to slide, across each other. For example, when you try to push a book along the floor, friction makes this difficult.

Friction always works in the direction opposite to the direction in which the object is moving, or trying to move. Friction always slows a moving object down.

The amount of friction depends on the materials from which the two surfaces are made. The rougher the surface, the more friction is produced. Friction also produces heat. If you rub your hands together quickly, you will feel them get warmer.

Friction can be a useful force because it prevents our shoes slipping on the pavement when we walk and stops car tyres skidding on the road. When you walk, friction is caused between the tread on shoes and the ground. This friction acts to grip the ground and prevent sliding.

Sometimes we want to reduce friction. For example, we use oil to reduce the friction between the moving parts inside a car engine. The oil holds the surfaces apart and can flow between them. The reduced friction means there is less wear on the car’s moving parts and less heat produced.

Ice causes very little friction, which is why it is easy to slip over on an icy day.

However, this is a good thing for ice skating and sledging.

Family History Research Project

This term we will be completing an investigation into our own family history!

Your task is to find out about your family’s immigration story.  For some of you, your parents or grandparents may have been the ones to immigrate to Australia. For others it will be someone further back in your family’s history. Students of indigenous background can research their family story to share with the class.

We will be working on this project at school, and in class. Some of the information will need to be collected at home (interview, biography information, artefacts, recipes). We will have time at school to work on researching the country, finding the flag and images, and finding maps. We will also have time to work on putting it together into a poster. If some aspects don’t get finished at school, they may need to be followed up at home.

I am looking forward to the chance to find out more about all of your families’ backgrounds!
