Lesson 4: Hei Mahi (Do Now)

Do Now:

Collect and complete this small 'Do Now'. Then glue into your SciPAD page 11. Use your commonsense when glueing - don't glue straight on-top of words!

Lesson 4: Exit Task

Find some space on page 15 of your PESS1.2 SciPAD,
and answer the following questions:

What does each letter in CUTLASS stand for? 

What is a Force?

A force is a push or a pull or a twist. 

Forces have both magnitude (size) and direction. The SI unit for measuring foce is the newton (N). 

Contact & Non-Contact Forces

There are contact forces and non-contact forces. When you push a box along the floor, there is contact. Whan a magnet attracts and pulls an iron nail towards it, there is no contact at first. 

What can Forces Do?

Forces can do the following things:

Balanced and Unbalanced Forces

If a force pushes an object to the right and another force of the same magnitude (size) pushes it to the left, these two forces will cancel each other out and we say the forces are balanced. The net force or the resultant force will be zero and the object will remain stationary. When balanced forces act on a moving objec,
