Quiz: Which force of physics slows humans down when attempting to climb over a tall steel barrier? A. Magnetism. B. Gravity. C. Friction?

-------------------------------------------------------

answers:
Andrew Smith say: The LACK of friction means I cannot grip on the barrier and cannot climb it at all.
It doesn't slow me down. It stops me completely.
I cannot climb this tall steel fence which is why someone wants to build one somewhere near Mexico.

I am slowed down on a long hill by the forces of gravity and friction.

JonZ say: Gravity would be the biggest force working against the illegals. Magnetism wouldn't come in to play unless they were carrying strong magnets, and friction wouldn't be a hindrance climbing up the wall, but may cause severe burns as the slid down the other side.
