Lakhmir Singh Solutions Class 8 Science Chapter 12: Friction

A force that opposes the relative motion of an object between two surfaces in contact is termed frictional force. This chapter deals with theoretical and practical learning, including amazing facts, information, and experimental descriptions. The chapter has a unique approach to teaching about the things going around with the principle behind their working intricacy. Thus, students have a grip on both understanding and analysing the concept much deeper.

The chapter further explains the surface irregularities that cause friction and their effect on nearby surroundings. Thus, students gain more deep-seated knowledge about the cause of friction and how various processes and regular acts depend on it. Factors affecting friction are well explained in the prescribed manner. The chapter outlines the types of frictional force, including:

  • Static friction
  • Rolling friction
  • Sliding friction
  • Fluid friction

The chapter addresses the advantages and disadvantages of the conceptual examples in a prescribed learning framework for better clarity of facts. Students get to understand mathematical ideas and develop the ability to utilise their knowledge in a new situation and apply it to a new context. The chapter provides vital information about the outcome of friction and how energy is consumed to overcome this force. This lesson further interconnects frictional force with spring force for a better conceptual perception that proves useful in higher classes.

This Science chapter on friction furnishes the ways to increase-decrease friction by using a variety of lubricants. The chapter further highlights the functioning and working of lubricants to optimise friction to our use. Students understand the basic involvement of friction in swimming, aeroplanes, and speedboat's streamlined structure, which helps students create a stable core by exploring these examples and a few others they may find.

The chapter further explains the difference between each type of frictional force and how these forces are useful and active in different situations.
