Question

I don't understand the concept question module 2, number 4. How can the velocity be increasing if the motion is clearly decreasing?

Answer 1

actually it's module 4, not module 2.

Answer 2

I think you're mixing up two different ideas. What's happening in graphs 2 and 3 is that the magnitude is getting smaller, but the velocity is increasing (it starts off negative, and approaches 0, thus it is increasing). However, while it is "increasing", this is causing the "magnitude to decrease" as it is approaching zero, and you can see this because it approaches v = 0 on the graph. Hope that clears it up.
