Unit 7 - Forces

Learning Outcomes:

• investigate examples of friction and the effect of lubrication (OP5)
  
• investigate the relationship between the extension of a spring and the applied force (OP6)

Hooke's Law

An animation to show that extension is proportional to load

Too little friction!

Ooooops!

Tyres

Different types of tyre are used for different surfaces

Sing along! 'Rubadubdub rubadub'

I know a song that will get on your nerves, get on your nerves.........

Fire by friction

Try this at home.. it's not easy

When Forces Go Wrong

Still want to Bungee?

Freefall - feather and a marble

Look what happens when we remove air resistance

Reducing Friction

What affect does the surface have on friction

Reducing Friction by design

This gets a bit complicated in places

Hot Brakes

Friction between two surfaces causes them to heat up

Phone Book Friction - 1

Join Jamie and Adam as they do science

Phone Book Friction - 2

Ask before you try this at home

The wind can be a strong force !

Don't worry... they weren't hurt

Another Hooke's Law simulation to experiment with!
