Nice animation, but I think there's some problems with the physics explanation.
Newton II: "In other words, a higher force results in a higher speed." This is wrong. ANY net force on an object will result in a higher speed if the net force in in the same direction that the object is moving. If the net force is in the other direction, then the object slows down.
I think you've also missed the point of newton III, which is that
when the ball hits the building, the building also hits the ball,
with the same force.

The explanation with the truck is unhelpful because there's going
to be friction from the ground pushing the container the other way,
and this is not mentioned. If there were really a steady force
on the container then it would steadily accelerate, as at the
begining of a fall.
I don't think the speed would necessarily halve when the second
container is added.

Newton II is f=ma, not f=m*speed.
