Momentum

Ship TurningQuick question:  If you’re going 30 miles per hour and wanted to make a 180-degree turn, how fast could you do it and how much ground would you lose heading the other way?

Quick answer: It all depends on the vehicle.

And that matters more than you may realize.

If you’re on a motorcycle doing 30, a good rider can execute a 180 pretty quickly and only lose a few feet before he darts back in the opposite direction.

On the other hand, if you’re at the con of an aircraft carrier traveling 30 knots per hour, it would take about 72 seconds. And in the process, you’ve lost about half a nautical mile.

Changing direction takes time.  And momentum isn’t always on your side. And because of that your resolve will be tested.
