Wrong. My chain can pull a 90 thousand ton aircraft carrier across the Atlantic ocean. Now put that carrier on land and let me try it. The key is resistance. So we have a chain that can pull 90 thousand tons of carrier with very little resistance across water, yet would snapped like a twig trying to drag 5 50 ton tanks across land.
Inertia is the resistance against being accelerated. If there is no friction then a piece of thread can pull any mass at a constant rate. But we are not talking about mere pulling something at a constant rate but accelerating something.
You have no basic understanding of physics.
Do yourself a favor.
Calculate the tension force on a cable (chain) in these two scenarios:
1. Pulling a 10kg in space (no friction) with an acceleration (not velocity) of 10m/s^2.
2. Pulling with 50N of force in a tug of war against an opposing person also pulling with 50N of force against you (the resistance you are referring to).
Which one gives the greater tension of the cable (chain)?
