In the video game "Mass Effect", there are characters (potentially including the player) who possess powers called "Biotics", which can be used to, in essence, telekinetically batter and generally abuse your foes. One power in particular, called "Throw", refers to the force of the character's biotic strike in terms of Newtons, ranging from 400 (I think) at the low end all the way up to 1000. Aside from some a beautiful physics engine rendering the affected enemy flying backwards at tremendous speed and landing in a crumpled heap, there's no indication of what any of this /means/. What does a Newton refer to? How "much" is it? Can you provide a real-life, easily understandable comparison (i.e., standing in front of a fully-loaded tractor-trailer doing about 65 mph)?
