      Picture yourself trying to catch up with a car going thirty mph, it’s getting away, then they slow to twenty.

      That’s a reduction is acceleration, just like a reduction in inflation means prices are still rising, but slower.

      This is a post about me at the grocery store.

        30-to-20 is negative acceleration (2nd derivative) causing a reduction in speed (first derivative) from 30 to 20.

        Similarly, inflation is a rate (like a velocity). A constant 10% inflation means prices rise at the rate of 10% per year.
