Only by bringing friction back into the conversation can we responsibly build out new technologies with growth potential and staying power.

In other words, in order to set a stationary object in motion, its static friction must be overcome first. If your coffee mug rests on a slanted surface, like an inclined ramp, then a frictional force ...

so gravity's pulling it down,it's got more space for water to push up against it,which means there's more drag,there's more of that friction with the water,and it gets slowed down more.Amazing!

Ice causes very little friction, which is why it is easy to slip over on an icy day. However, this is a good thing for ice skating and sledging. Friction is a force between two surfaces that are ...
