Behind all the supercomputers, machine learning, and exotic materials used to create modern speed are the basic symbols and ...

This friction builds up charges on different parts of the materials, producing a current — and ultimately, a static shock. “We developed a new model that calculates electrical current ...

However, if you try to slide the mug across the table then a friction force will come into play and initially resist your push until your pushing force exceeds the frictional force. In other words, in ...

This method has enabled a number of key conclusions on the mechanism of transition from static to kinetic friction in macroscopic systems to be made 4: (1) the onset of sliding is preceded by a ...

Perhaps few physical concepts have received less attention relative to their importance than friction. Learning the 'effective' notions of static and sliding friction, students of mechanics can ...

Flows inside ducts, channels and pipes are very important because they occur in many practical applications (water pipes, air conditioning ducts, gas lines, ventilation shafts, heat exchanger tubes, ...
