Yeah, I go to the gym a couple of times a week.



The first half of this module explores ideas about forces.  Students develop their use of technical scientific language in order to describe forces, practice measuring forces, learn to recognise whether forces are balanced or unbalanced, and calculate resultant forces.  The second half of this module builds on this and extends the work on forces to include ideas about pressure in solids, and ideas about moments and levers.


Ideas about pressure in liquids and gases are not covered in this module.  These concepts are introduced in unit 6.
