Hi there
⚙⚙⚙⚙⚙⚙⚙⚙⚙⚙⚙⚙⚙⚙⚙⚙⚙⚙
The frictional force that exists between two surfaces when a body rolls
over the other. Rolling friction is smaller than sliding friction.Rolling friction is less than sliding friction. Hence, sliding friction is replaced by rolling
friction by using rollers, like ball bearings between the hub and the axles in the moving parts
of machines and vehicles.
