Over-Acceration means what?

[YodasLuke]

You and I are going to have a contest to see who can push cars across a parking lot. Both cars are on a slight down slope.

When you push, you push as hard and as fast as you can with an explosive thrust. The car feels extremely heavy for an instant, and then it comes off your hand. (Over-Acceleration and loss of Lag Pressure) You hope that the energy that you have applied is enough to get it to roll across the finish line.

On the other hand, I start more slowly. I start to push the car to get it moving, but as it starts to move, I have the ability to push faster. I keep (lag) pressure between my hand and the back of the car. My car goes faster and faster as I pass the finish line, keeping pressure on the car.

As an aside, when I'm pushing on the trunk and you're pushing on the driver's door, we have divergent force vectors. But, that's a discussion for another time.
