Question

What happens if we do not reduce friction in machines
​

Answer 1

Answer:

1️⃣If we did not reduce friction in machines, it will requires more power to complete a work and results in wastage of energy. 2️⃣Also the heat generated by friction can disrupts and destroys the part of the machinery.

Answer 2

1. It will require more energy and power.
2. Also the heated part of friction can destroy the machine

Friction is a force that opposes motion; if the machine has moving parts, this means some of energy will actually be used to overcome friction (and get dissipated as heat) rather than do any useful work. 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.
