A-Iron Physics Question

[Steel Speedster ♂]

Imagine that you're a Lurcher and you're standing at the edge of the freeway. You suddenly Pull on one of the cars as it is passing by. What happens? Is it like tethering yourself to the car, causing you to instantly accelerate to the car's speed as you are Pulled behind it? Or does it accelerate you just as fast in the same direction as if the car was completely stationary (which almost certainly results in the car leaving your range before you catch up to it)?

Essentially, what I'm wondering is, does it make any difference if an object is moving when you Pull on it? When it comes to things like coins and bullets, there isn't much of a difference, because their mass is so small that it doesn't significantly affect the person pulling, but what happens when the moving object is much bigger than the person? Does the momentum of the other object get transferred into you, or is it merely an attractive force that accelerates the two objects towards each other?

This. Steel and Iron are just forces and their strength depends on masses of both the object and yours, distance and your Allomantic strength.
