Friction is one of the most important topics in Physics and it is important that you lay a proper foundation. Once these are understood, the topic on friction becomes an easier topic and it becomes easy to approach advanced level topics on friction. In this lesson we are going to introduce the topic on friction, we will look at:

• the importance of friction and its role in our everyday lives,

• the negative effects of friction and how you can minimize them,

• important definition of terms in friction you must know,

• two types of friction-static and kinetic friction,

• understanding a horizontal plane and inclined plane,

• labelling all the forces acting on horizontal and inclined plane

• laws of friction and the angle of friction

• coefficient f friction,

• exam type questions on friction.

The lessons comes with exam type questions that will help you understand the topic from an exam point of view. The videos on each topic provides clarity on the topic on Friction especially the inclined plane and the horizontal plane. Resources are also included at the end of the lesson for more practice on the topic.

To be able to understand the module, it is important to give yourself the practice questions provided and see how you will perform before going through the whole video. This will give you more practice and enable you to correct yourself.
