Answer:

1. If there was no friction it would be impossible to move in any direction other than down.

Explanation:

Friction stops things from sliding apart. If there was no friction everything would slide to the lowest point. It would be impossible to climb up anything. Imagine trying to climb a wall of ice without crampons and an ice pick. It would be impossible.

From the human perspective, it would be impossible to stand up or even move. Simply crawling requires a force to make you move. That is provided by friction.

With no friction the only possible movement would be falling to a lower point under gravity.

2. A lack of gravity would eventually take its toll on our very planet, writes Masters. Earth itself would most likely break apart into chunks and float off into space.Without the force of gravity to hold it together, the intense pressures at its core would cause it to burst open in a titanic explosion.
