Physicists in the US have made a peculiar discovery about how a small object slides over a rapidly rotating lubricated disk. They have found that if the object is tilted so that it only touches the ...

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 ...

IT is universally assumed that the force resisting the sliding of one body over another acts in a direction opposite to the relative velocity. However, no recent test of this law appears to have been ...

The relationship between friction and load, quantified three centuries ago, has an exception when the interaction causes magnetic realignment. The discovery won’t let you off the hook when dragging ...

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 ...
