Thanks.
What explains the continued momentum of objects inside the truck as brakes are applied ? ( the example of my relative with the van )
The objects within the vehicle are slowed by the application of the brakes, since they are contained in the body being slowed.
But yet they continue to fly forward..

The only way that I could think that a moving weight might help is when coasting on a decline.
I'm guessing the movement of mass from gravity might give a slight boost in coasting ? ?
Think of a semi with a trailer full of loose cargo.
If it suddely coasted downhill, and the load slid to the front of the truck, would it do anything due to ( gravity ? )

I know this is all 3rd grade science here. Sorry.
