Question

how can we can reduce the friction of machine​

Answer 1

Hey

Friction of a machine can be reduced by using ball bearings

● They are used in the moving parts of the machine to reduce friction

● The substances used to reduce friction are called Lubricants

● Many lubricants are used to reduce friction in machines

Answer 2

Answer:

WAYS TO REDUCE FRICTION:---

• Use lubricants{A substance, for example oil, that makes the parts of a machine work easily and smoothly}
• Make the object more streamlined.
• Use of ball bearing.{Best example is fidget spinner(a playing toy through which child play by rotating it's wheel)which uses bearing to make rotating till long time and without opposition of much friction.}

WHY WE REDUCE FRICTION:-----

This reduces the efficiency of the machine and means more energy is required to do the same amount of useful work as a result of friction. Therefore, if we reduce friction, we can reduce the energy dissipated in overcoming friction and increase the machine's efficiency.
