Knowledge and Understanding 119 Introduction In this topic you will be learning about Newton’s laws of motion and how they can be applied to problems where several forces act. You will also come across frictional forces, which until now we have regarded as negligible as the surfaces touching have been smooth. You will look at the systems you looked at in AS except now the systems are more complex with the introduction of frictional forces and sometimes the particles being considered are moving or in equilibrium on a slope. This topic covers the following: 7.1 Newton’s laws of motion 7.2 Motion on an inclined plane 7.3 Friction and the laws of friction 7.4 Limiting friction and the coefficient of friction 08/03/2019 14:32 Topics start with a short list of the material covered in the topic and each topic will give the underpinning knowledge and skills you need to performwell in your exams. The knowledge section is kept fairly short leaving plenty of space for detailed explanation of examples. Pointers will be given to the theory, examples and questions that will help you understand the thinking behind the steps. You will also be given detailed advice when it is needed. The following features are included in the knowledge and understanding sections: • Grade boosts – are tips to help you achieve your best grade by avoiding certain pitfalls which can let students down.
