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 ...

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 ...

A motorcycle leaning hard into a turn looks sort of like magic. Of course, the whole process is actually governed by some basic physics. In short, the motorcycle leans in a turn because of torque and ...

The frictional properties of any plain bearing depend on the lubrication system. Either hydrodynamic or hydrostatic lubrication can provide low friction. Gas bearings have the lowest friction levels.
