Maybe I should just turn this blog into the post-Car-Talk discussion forum. In this week's episode of Car Talk, Tom and Ray talk to a lady that would like to turn her Subaru into a snow plow for her ...

What determines how quickly a car can stop? How do tires and brakes affect braking distance? This video explains an equation ...

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 ...

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 ...

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 ...

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.
