Skoltech researchers have explained why very weak friction obeys different laws than those governing regular friction as we know it from school physics. Among other unexpected and counterintuitive features, the alternative friction laws formulated by the team reveal why increasing the weight of a body sliding along a surface does not necessarily cause greater friction.
