If friction vanishes suddenly then,
Cars would be faster because there would be nothing to drag them back and there would be no grip so the two would be very dangerous imagine a car was out of control at very high speeds and with nothing to slow it down.
Cars can not start moving if there is no friction (only the cars with JET ENGINE can start).So the first answer is OK if the friction disappears while the cars are moving.
It disappeared
yes
There is no motion
the electrons move away
They won't be able to stop.
What would happen next if sagebrush is disappeared frrom a desert?
if the oxygen
You would die.
Everything would die
You would die.
It disappeared
The friction will go down drastically.
If friction is more it leads to unwanted things
its magic, it disappeared and its probably happy somewhere else
yes
This cannot possibly happen, so asking what would happen if it did happen is an exercise in stupidity.
If plants disappeared from earth, all life on earth depending on photosynthesis would disappear.
