Really, this is the experiment I wanted to start on. How does friction work in Bad Piggies? Let me start with a quick summary of my experiments so far. Scale. For the size of stuff in Bad Piggies, I ...

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 ...

Researchers have demonstrated how to entirely suppress static friction between two surfaces. This means that even a minuscule force suffices to set objects in motion. Especially in micromechanical ...

Probably everyone is familiar with the phenomenon: water drops cling to a pane of glass, if it is tilted out of the horizontal plane. Only when a certain angle is reached they slide off. This raises ...

Frictional forces play a role in many activities – riding a bike, going bowling, and even lighting a match. When two surfaces rub together they create friction, which works to slow movement down. In ...

Quick, out behind the bike shed, Professors Pendry and Leonhardt are having a fight over a completely hypothetical situation. If we hurry, we should catch the end of round three. Science: it is ...

Introduction Sometimes friction can be annoying. It can make it difficult to push heavy things like furniture and it can even give you a nasty scrape if you fall. But friction is actually very ...

A control system for deformable robot-fingertips was developed for grasping and releasing objects. Previously developed robot fingertips with high friction texture can stably grasp a paper box, a soft ...
