Here's another, more dramatic, example of the strength of electromagnetism vs. gravity.
Suppose you fall out of an airplane that's 10 kilometers up (about six miles). In 45 seconds, you hit the ground at 443 meters per second. It took 45 seconds for gravity to accelerate you to that speed.
But it'll only take a fraction of a second for the normal force (electromagnetism) to decelerate you.
