## 6 Forces in Equilibrium

This is a unit where you can really go to town on the problems with the vectors. You must read the specification carefully and make sure that you don’t panic if you can’t do all the problems in the post. I have included lots of vector problems which go 360° where the exam board will …

## 7 On The Move (Motion)

The trick to this unit is simply to do lots of calculations over and over again. Test out what you think, try out the animations and you will be able to do the exam questions. The nuts and bolts are important for every calculation. Try to set up each problem with a diagram and then …

## 8 Motion and Force

This is a unit which really many find quite difficult. To help yourself out you must learn Newton’s 1st, 2nd and 3rd law of forces. Without this knowledge you cannot succeed in explaining or reasoning out most questions. Also there is a basic principle of coplanar forces producing a resultant and therefore acceleration. It is …

## 10 Work, Energy and Power

This work builds upon the Y11 work from Additional Science. You should be able to derive the Kinetic Energy formulae, understand the concept of work done and how that can be expressed as an idea of Power. Also the efficiency of devices and some idea about how to apply that to real situations such as …

## 11 Materials

This unit depends on an ability to explain and understand force extension and YM graphs. It is one of the easy topics but also easy to drop marks if you don’t learn the graphs. Also take care of your areas and units as mm don’t convert well to m when you square them for an …
