Ocean Liner QM2

[huggins]

If I pushed against the free floating QM2 would it move and why.

[mibn2cweus]

A force applied by one object on another is accompanied by an opposing force of equal magnitude. This results in a change in motion in proportion to the mass of each object where the freedom of motion is not otherwise restricted.

In other words, �not much�

[Teddio]

Yes because your push force would cause the ship to accelerate in the same direction as the force. There is no retarding force at the exceptionally low initial speed as the ship is floating in water. Contrast this with pushing a 120 ton locomotive on steel rails with its brakes off. It won't move because the static friction force is much greater than your push force.

I don't know if there is a law for it but I believe huge objects are attracted to each other without any external force or gravity.
