Question

what we need to do to reduce resistance to the motion?​

Answer 1

Answer:

we need to increase friction

Explanation:

the resistance that one surface or object encounters when moving over another it is called FRICTION

Answer 2

Methods to reduce friction to a motion:

• The surfaces in contact can be polished such that they become smooth and the resistance is reduced.

• In case of motion in fluids (water and air), the objects can be designed to have a streamlined shape in order to reduce drag and resistance.

• Use of lubricants and oils fill up the small undulations on the surfaces in contact resulting in smooth sliding of one surface over another.

• In case of rolling motion , friction can be reduced by use of ball-bearings as in cycles and bikes, etc.
