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 ...

This is a preview. Log in through your library . Abstract The purpose of this paper is to improve the understanding of static friction and the factors which influence it and its measurement. This ...

Keywords: Seismic performance. Nonstructural components. Static friction coefficient. Kinetic friction coefficient. Rigid blocks. Block-type components. Tilt and pull tests. Dynamic analyses.

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 ...

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 ...

I don't normally watch many NASCAR races, but I do come across some NASCAR videos online. Sometimes these clips become the basis of a great physics problem. In this case, it's a 21-car crash at the ...

At a busy street crossing, people wait for the signal to change. When one person steps out first, others soon follow.

A spinning tool plunges into two pieces of metal, rotating at a high rate of speed. As the tool begins to move, it softens ...

Michael Graham Richard is a writer from Ottawa, Ontario. He worked for Treehugger for 11 years, covering science, technology, and transportation. So what is kinetic energy? There's motion everywhere ...
