Question

What will happen if we don’t reduce friction from machines?

Answer 1

Friction from machines:

1. Friction is an opposing force towards the relative motion.
2. Firstly, if we do not reduce friction, we have to apply more power to complete a particular work and this results in wastage of energy.
3. Then the wastage of energy due to friction in terms of heat can cause mechanical damage to our system.

Therefore, it is important to reduce the friction as much as possible in our machines.
