Question

If friction is vanished what will happen

Answer 1

Answer:

You couldn’t walk, because everything would be slippery and Work done by friction would be zero, and which mean, while solving your high school Physics Problem when you ignore the heat loss due to friction it would become physical. There would be be no supersonic space crafts as every Boeing would be able to achieve sound speed. And the heat you feel while rubbing your hand won’t happen. And do nomad people would suffer, as no friction ⟹ no fire.
