Question

Imagine that friction disappeared from the earth. What will happen?Explain.

Answer 1

Answer:

Friction is a dissipative force responsible for inhibiting the relative motion between two surfaces in contact. Now, if friction disappears from Earth, it will be become a dangerous event because of the following reason: Friction provides retarding force to moving object as a result of which they come to rest.

Everyone will end up either at the bottom of walls, rocks or holes or sliding around. Unable to move and slowly dying through lack of water or dying from broken bones. If earth suddenly lost friction we'd all die in massive earthquakes and tsunamis as all the pent up tectonic energy everywhere is released at once.
