Question

what if there was no friction and what would be the situation of vehicles and humans​

Answer 1

We wouldn't be able to walk, but we would also be able to move for very long periods of time over long distances due to the lack of friction slowing us down. ... Not only would there be a lack of friction between surfaces, there would also be a lack of air resistance due to the loss of molecular friction.

Writing on paper with a pen is also possible due to friction. Everyone and everything would be sliding all over the place, including the water in lakes, rivers, and oceans. Friction is a force that tends to stop motion or resist the motion of objects. ... Walking would be impossible without friction.

Answer 2

$\huge\underline\orange{\mathcal Answer}$

• You wouldn't be able to walk (it would be similar to walking on ice but even more impossible)

• Computers would never overheat, so technology would be able to improve massively

• Knives would be much less effective.

• The Olympics would be pointless. All events would be reduced to a test of strength pushing away from the start.

• Cars wouldn't work. The wheel's would spin.

• Everyone would have to wear nappies.
