Answer:
To reduce friction we can make the surfaces in contact smooth. ... Another method of reducing friction is by using bearings. When ball bearings are introduced between two surfaces friction is reduced because of the freely rotating metal balls. To increase friction, the surfaces in contact have to be made rough.
