Acceleration is a change in velocity.

Think about what's happening to the movement in time and space of this thin ninja. How is s/he "speeding up?"

Since the intervals are increasing in distance in increasing amounts, the ninja is speeding up exponentially.

This ninja is accelerating at a constant rate because the distance intervals are equal.

However, if you read Bruce Palmquist's comment below, you must remember this:

" Your middle ninja is accelerating at a constant rate. But that rate is zero because her velocity is constant."

This ninja was accelerating at constant pace (see first four intervals) but then decreased acceleration (last three intervals).

What acceleration do you see with this ninja?

How could you apply ninja's in your class?

Thanks for all of the extra information in your blog. I (Bruce) want to comment on your forward slash ninjas. Your middle ninja is accelerating at a constant rate. But that rate is zero because her velocity is constant. So, while your statement is correct, it may be confusing to students who confuse velocity and acceleration... meaning nearly every student because even my college students confuse these terms.
