Why it is not wise to reduce friction in every situation? Explain one situation where reducing friction can be dangerous to us
Answers
Answer:
On road friction is dangerous to us.
Explanation:
Because if we reduce much friction on road then cars can slip and then there is danger of accidents.
Answer:
Walking won't be possible it will be similar to attempting to walk on ice but being unable to secure a grip. So, with less friction, the walking situation becomes almost impossible.
Explanation:
Friction is frequently described as a "Necessary Evil".
In some circumstances, it is absolutely necessary, but it also decreases efficiency and causes wear and tear.
What is its purpose?
Imagine running a bicycle on a frictionless surface. You won't be able to move all as there is no force to push you in any direction. Hence, you need some friction . Also, you need friction in order to make the bicycle brakes work otherwise you may not be able to stop it and may met an accident.
So why is it bad?
It decreases a mechanical system's efficiency and causes wear and tear.
The force of friction requires a system to expend more energy in order to overcome. As a result, efficiency is decreased.
Friction also reduces the lifespan of mechanical parts since they deteriorate over time.
