1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...

Friction represents obstacles to change. Most people try to push through friction instead of reducing it.

Learn about friction cost to make better informed decisions: its implications in investments and loans, and how it helps assess the true cost of financial transactions.

The field of economics has long modelled itself after Newtonian physics. When physicists analyse a complex problem, they usually begin with the simplest version and neglect any complicating effects, ...

Irregularities present on a surface are often described as surface roughness or texture. These surface textures such as grooves and dimples impart friction, which is the force between two sliding ...

Customers, as we all know, are a fickle bunch. Considering how customer loyalty is far from abundant these days, there are many ways to lose a customer, but the biggest turn-off for today’s consumers ...
