Question

what is the SI unit of coefficient of friction

Answer 1

The coefficient of kinetic friction is the force between two objects when one object is moving, or if two objects are moving against one another. The coefficient of friction is dimensionless, meaning it does not have any units. It is a scalar, meaning the direction of the force does not affect the physical quantity.

Answer 2

जब एक पिंड दूसरे पिंड पर सरकने का प्रयास करता है, तो लगाए गए बल की प्रतिक्रिया स्वरूप घर्षण बल कहलाने वाला विरोधी बल पैदा होता है और विपरीत दिशा में काम करता है.
