The Hindu: The physics of friction, the ‘necessary evil’ that bedevils daily life
I'll be honest—friction is pretty complicated. Imagine that I have a block of wood sliding on a table. In some way, the atoms on the surface of the wood block are interacting with the surface atoms on ...

In today's episode, Shini tells us about Static and Kinetic friction. Why is it hard to move a heavy bookcase across a carpeted floor? And why is it easier to keep it moving than it was to get it ...
Friction is an intrinsic physical phenomenon to curling. Without it, objects in motion would move endlessly, without slowing down. This would cause many safety-related problems: Cars or trains could ...
Perhaps few physical concepts have received less attention relative to their importance than friction. Learning the 'effective' notions of static and sliding friction, students of mechanics can easily ...

Friction is now archived and no longer receiving submissions with this publisher. All articles published in the journal during its time with Springer will remain fully searchable through our websites.
Friction is an essential part of human experience. We need traction to walk, stand, work, and drive. At the same time, we need energy to overcome the resistance to motion, hence, too much friction costs excess energy to perform work, introducing inefficiencies. In the 21st century, we are facing the dual challenges of energy shortage and global warming from burning fossil fuels. Therefore, the ...
10.1 Introduction In this chapter, we will only investigate the dry friction or Coulomb friction between two solid bodies. Friction between solid bodies is an extremely compli-cated physical phenomenon. It encompasses elastic and plastic deformations of the surface layers of the contacting bodies, interactions with wear particles, micro-fractures and the restoration of the continuity of ...
Friction is the resistance to motion which is experienced whenever one solid body slides over another. The resistive force, which is parallel to the direction of motion is called the ‘friction force’. If the solid bodies are loaded together and a tangential force is applied, then the value of the tangential force which is required to initiate sliding is the ‘static friction force’. The ...
Friction is a fundamental force that impacts almost all interface-related applications. Over the past decade, there is a revival in our basic understanding and practical applications of the friction. In this review, we discuss the recent progress on solid-liquid interfacial friction from the perspective of interfaces. We first discuss the fundamentals and theoretical evolution of solid-liquid ...
